Why not make your Halloween designs last forever?! You guessed it these are all concrete!…
This is so mysterious that I get email questions about Eco printing all the time! I really do know how it is; as I had many of the same questions when I first started. Let me help you out a bit with my Eco Printing tips & Tricks.
You have to start somewhere:
I know how you may feel; you see some amazing Eco Print and think it’s really just that simple! ‘Roll up some fabric and leaves and steam (or boil) and you get an amazing print, right? Well maybe, but probably not. I went through quite a few early attempts and with each would learn something. Some of my first prints looked like I just drove over them with my car; dirty blotches. But I was determined to figure it all out; and I would not even attest that I have, but I now have some (yes some, no one does get all) control on the results.
Many who have figured it out with their experimentation are not that happy to just give away the secret recipes, hence there are quite a few expensive workshops. Myself; well, that stubborn streak in me sent me on a mission.
Finally some prints:
When I look back at my first true prints I chuckle now; they were exciting at the time but I see how I have progressed in these years of making bundles. They were basic and heavy on the use of iron.
I had started to learn that preparing the fabric is so important! Do make sure the fabric is super clean by scouring well. Also, mordanting according to what fibre you are using makes all the difference. Eco printing on cotton and other cellulose fibres are quite a challenge. Soy milk dips and drying make the cellulose fibre become somewhat ‘protein-like’. As of late I have have been using homemade Aluminum Acetate with quite good results as with the Maple Leaves.
It’s how we roll:
Even with perfectly prepared fabric things can go awry. How it is bundled can also affect the outcome of the prints. This is a contact type of mark making so it has to be tight and flat. I dry my leaves to store for later use so they are quite flat (rehydrate before use).
Another issue about bundling is ‘ghosting’ which happens when the prints travel through the layers of the fabric. It’s all about what you prefer but I like clear prints so I use a barrier layer. I use a plastic barrier made from drop sheets and reuse many many times. Paper or other fabric can also be used and then have another purpose afterward.
If you look closely above you will see the lines across the maple leaf. The string wrapping was not dense enough and this translated into the striping across the print.
Making sure the bundles are tied really tight is important. Stay tuned (post coming soon) for my unique innovative method for tight tying without the cut fingers.
‘Why is my print so blurry’? The amount of wetness is also a possible problem in Eco Printing. If there is a lot of water it can flow and leak through causing blurs. I suggest that you wring as best as possible and also don’t submerge the bundle in a water bath to simmer. Some fabrics like thick wool have added challenges as the amount of contact is less due to fibre size and may need extra moisture. That is why tests should be done.
Perfect recipes are not quite easy in this art form as the variables are so great.
Drying & Storing leaves:
I found out the hard way that using books to store leaves is not a good idea. The uneven pressure and tight quarters makes for mold growing when attempting to dry the leaves. Too heavy weight on the stacks will not allow air to pass and dry the leaves.
Which Side is best?
When placing the Leaves to Eco Print there is also the question about which side to use. The top side is usually a brighter colour but that does not mean that it will give that colour print. The cells on the bottom vein side of the leaf have thinner walls so they print easier. However this may be one way to achieve the type of print you prefer so it’s not a rule…
All are not Equal:
Don’t be fooled by fancy colours or shapes; not all leaves print well. It is not the colour on the leaf but the tannin that it holds. Every country has it’s best ones and more are discovered by testing all the time.
But there are still ways to use the lesser performers in a resist method.
I love my many maples as well as rose, sumac, weigela, some oak, plum not to mention the wonderful eucalyptus available to some.
Take note how colours are not printed as they were. There are ways to have brighter colours but rarely the exact colour seen before steaming.
Protein Fibres print well:
It’s inexpensive to test on old cotton sheets but lovely silk fabrics prints so easily and well. How exciting is it when the bundle gives you the hint of great things to come?! Don’t despair when not every print is great.
Wool is also a protein fibre and also loves to accept the tannic prints. Wool does not hold moisture well so it brings it’s own challenges but it’s worth it!
Oh, the Iron Question:
When I first started Eco Printing I thought it was great that I could just make my own rusty iron water to aid in the printing. It is true but sometimes I would not know exactly how strong it was or what other metals were in it.
I now use fresh iron water solutions that I make with Iron Sulphate. Do I have an exact recipe for the strength? No, as I like to vary it and sometimes take an artistic risk to see what might happen. It’s art and I don’t measure my colours when I paint either. But it may be a good idea to keep notes…
Look at this leaf (above)! That dark marking is the reaction of the natural tannins and the iron solution; the basics of eco printing. It was a leftover leaf in the iron water.
Why Are my prints so dark?
Yes, I love what iron brings to the art form most of the time! It’s been an important player in the history of dyeing and pigments but it can also be frustrating. Here the prints are quite dark and dulled due to an overuse of iron. Thinner and lighter fabrics need less…
Where does this colour come from?
When you see some amazing colour in Eco Printing it is often from a combination with a natural dye. Madder Root, Cochineal and Logwood all bring amazing colours and effects to the table. Other ‘helpers’ such as tannins can come in the forms of teas, such as Myrobalan and Pomegranate.
Look at all the amazing combinations of colours! Even indigo can be brought into the mix before or after and eco printing round.
Some great Byproducts:
It’s a lot of Science:
I won’t even pretend that I am a science-pro but I am a good observer! Eco printing is a testament to reactions of PH levels. Many colours from natural dyes are so sensitive to acids that amazing magical things happen! What was all one bright pink is now many colours of the rainbow! How wonderful can nature be?!
Can we really anticipate exactly what result we will get?! I think not! If we could then it would not be as interesting or give us the drive to take on the challenge.
Go Ahead and get your fingers dirty!
Yup, fingers of all colours! These are ‘cochineal’ pink since we are a ‘protein fibre’! Other times mine are dark from iron staining. But don’t worry a soak in some lemon juice (or citric acid) will brighten and clean them up!
You’ll collect a few buckets (for soaking, mordanting, washing and dyeing) and be seen bent over picking up leaves quite often!
