Many years ago precious pure wool blankets used to be the staple of a household. Nowadays they are being given up as the newer lightweights push them out of the linen closet. Lucky for us eco printers as they can now have quite the second life! You will love the Wonderful Wool Eco Printing and then go raid some linen closets…

Wonderful Wool:

As with the mittens wool can be used for so many things. These blankets came in many weights, quality and even colours. Some have been carefully stored and some have been washed and used. Depending on the weight they can become coats and jackets or accessories such as bags and scarves. Wool wears great and is not as fragile as you may think. Some have developed quite a ‘felting’ over the years. There is a lot of yardage in a blanket as well!

One of the easiest plant materials to dye wool is onion skins. Even with just a bit of pre-mordanting with vinegar (50% water for at least an hour) the wool prints oranges & reds easily with the skins. As a way of making shapes I cut them with some spice scissors.

I relied on my favourites such as maple and rose leaves as well as a newcomer; ‘wine weigela’. They have been pressed between newspaper until ready to use. Even after quite dried they can be reconstituted again.

This time the iron mordant is in the form of a soak in rusty iron water. I maintain a bucket of railroad spikes and water that I refresh with some vinegar now and then. I soak the leaves for about 30 minutes at least. Don’t be too strong with the iron as it will be harsh on the wool fibres and make it feel even scratchier. As with most of my projects I will do small test runs before investing a huge precious piece.

The wool tends to soak up a lot of moisture. It will keep dripping out the excess water as you work so its best to squeeze as much out as possible. Do not wring it as that may distort the wool. The prints will not be distinct if too wet. A towel to squeeze in will help wick the excess water.

Blot excess ‘iron-water’ from the leaves as well. Keep in mind that front and back print differently.

My intention was to have some background colour using the small flakes of onion skin. Be creative and unique. There are so many possibilities.

As an assurance that any prints will not bleed through to other layers, I cover in plastic (drop sheets are easily cut to the width and can be reused many times) before rolling.

The Rolling:

The wool blanket starts quite thick and fluffy. I find that tying tight with string can cause deep indentations that are pretty permanent. I came up with my own unique way of keeping the roll flat but also still able to breathe. Much like sushi rolling, I use a bamboo placemat on the outside of the roll. As you see wool can get bulky quite quickly.

Processing:

Another option is to leave some wool exposed to create interesting edge design by immerse boiling in some dye colour. The string/twine will act as a resist and I have often see it look like wonderful fringes on the edges.

If you would like a cleaner background and distinct prints then steaming for about 2 hours would be best. For some variation of colour and edges boiling would give more results. The addition of some dye stuffs ( leaves, onion skins, iron ) in the pot will add some colour.

The Reveal:

Once you have steamed or boiled they can be opened. I often like to keep some of the heat and let it cool slowly by wrapping in a thick towel/blanket rag. Anticipation… until the reveal!

Such wonderful reds! Since wool is a protein fibre it prints great. The pressing of the rolls also changes the feel of the wool and it becomes a more dense fabric.

They remind me of wool coat melton; thick and sturdy.

You just never exactly know what you are going to get! The wine weigela printed with slight reds and mauves. 

The Amazement:

Wonderful wool eco printing!

Oh, what to make with the great prints? How can I sleep with so many ideas floating through my head?! Pillows? Bags? Jacket? Journal? Vest? Quilt?

Alright, alright, here’s a sneak peek… I had better do this before we hit the heat of summer again…

  1. These are amazing.I make owls from felted vintage wool blankets so I have a large stash on hand in every color.Could you use flowers like pansies?Our winters are long up here in Saskatchewan but spring can’t come soon enough to try this.

    1. I know what you mean… as I’m in Canada too! We just had a thaw but still not going to cook outside! (I’m currently testing some other methods) But the oven can work as well if you have a really good ventilation method as some smells can be aggravating. Flowers seem like a good idea but most don’t create a colour that stays or can handle the heat. Experimentation is the key here. You can use felted blankets, even handfelted wool. Many use upcycled garments. It becomes an addiction I’m afraid as you never know exactly the outcome! Welcome to eco printing!

      1. wow Barbra,This was a great amazing email.
        You create so so much! I loved this wool eco-but never knew the Mordant!So 50/50% cheap vinegar and water?oka..may give this a try.
        Thanks for all your shares.Debra/Nantucket

  2. I am always interested in seeing the gorgeous results of Eco dying and the different techniques and processes used. What a fantastic idea with the herb scissors and onion skins. Absolutely love the detail photos of f the coat. Stunning!!! Well now I have to keep an eye out for a white or cream wool blanket when thrifting🤔. I found you through Pinterest. I am also Canadian from the interior of BC. Thank you for sharing your knowledge 😃

  3. Such gorgeously detailed information. Thank you for being so generous. Can you use wool blanketing that normally sold for embroidery to make cot blankets? I can’t wait to try using the coloured squares blankets. Thanks again. I am in Australia where all the gum and eucalyptus trees roam.

    1. Oh aren’t you fortunate to have eucalyptus in your own backyard! Some euca prints the most amazing reds! I have seen many print on old wool garments and coats so I think the wool blanket would work as long as it’s 100% wool. Nowadays its harder to buy fabrics that are not some polyester mix. To test unknown fabrics my mom used to burn a thread. If it melts it isn’t wool, if it smells like burnt hair then its prob wool. I always suggest small tests first…

  4. I have discovered your site and a wealth of inspiration along with it!
    One question: how do you safely clean the eco dyed wool?

    1. Since wool is actually a hair you could use a simple mild shampoo. I use a PH neutral soap like Dawn. Do not wring wet wool. Squeezing is better…

  5. I just read this site. I’m glad I found it! You have great tutorials!
    I bought a used white cashmere blazer that I am anxious to try this method with.
    I have dyed many (used) wool blankets…. gives them new life. I love wool. It breathes!

    1. That’s great. I would still do a test run if you can. But sometimes I just ‘dive’ in as they can be overprinted or lightened with citric acid/lemon juice if needed… I am a bit of a collector of vintage wool blankets too!

    1. As much as one would think that all the great colour would print its does not. I do get some rather darker prints from some of the rich colour leaves though, esp the maples. It’s all about giving it a try… you just never know!

  6. Your work it’s amazing! I’m startint to try with my local trees and bushes, I live at Chile, south, and I want to boil every plant 😉
    Thank you so much for sharing your experience. You are a great artist!

  7. I was so lucky to find a deal on wool at fabricland and now i wanted to do a shawl with my purplish wool/acrylic 40%. I would love to paint it and maybe do ecoprinting. Since it is mixed, I was wondering i should simply stick to light fabric paints. This is so exciting for some reason. Hope to hear from you all and barb too!

    1. I have not painted wool at all. This eco printing is more related to dyeing than painting. Unless you use a thickened dye to paint with I am afraid it would be stiff and look very thick on the fabric. You could add interest with tie dyeing (adjust for wool) or shibori There’s alot of possibilities… The acrylic part will lighten any possibility of strong colours though.

  8. Impressive! I was attracted to my interest!
    You also soak the wool and plants in 50-50% vinegar? How do you record when you’re done, do you understand, steam? How many degrees can I have in the oven? I’m really curious to try it.
    Thank you for responding!
    I wish you good luck!

    1. Thanks! I do not use the oven, I steam above boiling water or you can also simmer in water. I do not dip the leaves in vinegar, only the wool. Do tests to see what works best for you. Have fun

  9. Hi,
    You really surprised me with your lovely behaves, not selling each information you know, not only this, but you even share all what you have learned through years without hesitation.
    I sew many famous names in eco printing refusing even to reply to a question with no or yes, not to mention an information. You feel like you are asking her to give her kidney!!!

    Many thanks and my best wishes.

    1. Yes!! I know, when I started I felt like I was solving a crime bit by bit until it started to all come together in pieces. I am sure some are not too happy with my free sharing. I do spend a lot of energy so any support is appreciated and you may also see my store

  10. WOW I read every word you write with anticipation – thank you so much for the effort you go to to freely share your knowledge with us all I found you on Printing with Botanicals fb page when you posted about microwave printing Ive tried it and love it thanks so much. Ive just read the post above and am a little confused which happens easily lol what is soaked in the 50/50 vinegar and water and what is soaked in the iron water. Im in Northern Australia and wool is not as prevalent as it used to be and as Im in a tropical climate we just don’t need it nor wear it so its hard to acquire. Im a thrift shop regular and occasionally pick up a wool blanket but have been donating them to the wildlife sewing group that I volunteer at to use for kangaroo and wallaby stands to replicate a mothers pouch for orphaned joeys but Ill be keeping the light coloured ones from now on – sorry wallabies lol. I have hundreds of eucalyptus with the mandatory koalas in them on my property so have no shortage of those leaves but not much else sadly everywhere I go now Im always eagle eyed at the leaves on the ground and whats growing Ive pulled the car over many a time to grab something that I think might produce a result – its all a learning curve I guess. Once again thanks for your time and effort – regards from Australia Ill pop over and donate to your blog

    1. Such a nice story! It is amazing considering how far away you are from me! I can’t imagine Koala’s in your trees! Well, I guess we each have our pros and cons!
      The stuff that is dipped in the iron water is the foliage. As you see in the groups it can be one of a variety of combinations and more are being discovered every day. I am an illustrator and could just paint what I want but there is some magical allure to the uncertainty that this Eco Printing gives! Thanks for the donation! I’m itching to get an order of silk… having some withdrawal.

  11. Thank you so much for this detailed page. I see on another page you have mentioned Eucalyptus leaves. I am based in Sicily and have them in abundance. I was wondering, do I need to put them through an Alum process like you have with your leaves? Or will they print on simply Alum mordanted fabric with Vinegar? Other notes I have read don’t mention actually mordanting the leaves which is why i’m curious.
    Thank you!

    1. I do a fair bit of research and the euca can print amazingly especially on a protein fibre. It does depend on the type though. Wool and silk sound like they need little prep for euca. It might be worth a small test run… The alum is usually for the fibre not the leaves. Good luck…

  12. Hi Barb,
    I am so excited to have found your wonderful site with so much knowledge and inspiration. I can’t thank you enough for being so generous to share! You are a gift! You have made this art form so much fun and exciting for me!
    I would like to ask where you found the plastic that you use when you bundle your leaves? I have been using the crock pot oven bags but not reusing them and I’m not sure if other plastic will melt to the garment during the steaming process.
    I’d also like to know where you purchased the cochineal, the root madder and the indigo? I would like to try my hand at these beautiful colors.
    As always, thank you for your help! Gail

    1. I use strips that I cut off plastic drop sheets meant for use when painting.They are quite thin. It allows me to just cut the width I like. I don’t use a pot or steamer lately; I use the microwave and I reuse the plastic many many times as it does not melt. I’m pretty sure there may be some who are not too happy with my free sharing as workshops are very expensive! I am self taught… with the help pf the ‘net!
