Shibori eco-printing on cotton

Following on from my recent post about combining shibori dyeing and eco-printing on wool, here are some similar effects achieved on cotton. I really enjoy combining organic eco-prints with geometric grids or lines from shibori dyeing methods.

Liquidambar leaves eco-printed on cotton with iron and alum mordants

This pattern was created by folding the tshirt up into a small bundle, adding liquidambar and Japanese maple leaves as I went. Then I tied it tightly with string and submerged it in a dye bath of eucalyptus bark and iron, cooking it for about 1 hour. The fabric was mordanted with homemade iron and alum mordants, following the instructions in my ebook, Gum Leaf Alchemy.

Cotton naturally dyed with eucalyptus leaves and bark

Here is a close up of a similar pattern, this time with eucalyptus leaves and an iron mordant. The large section of lines show which part of the tshirt ended up on the outside of the bundle, wrapped tightly with string. There are smaller sections of lines where other parts of the tshirt were also on the outside of the bundle, because of how it was folded.

This long-sleeved tshirt was also folded up, but into a smaller bundle which was pressed between two square pieces of hardwood. This helped to create a very even, geometric pattern to contrast with the organic shape of the leaf prints. This piece was also mordanted with iron and alum.

This piece of fabric was mordanted with iron, covered in rose leaves and folded into large squares. I pressed the fabric between 2 tiles, clipped the tiles together then submerged the bundle in a dye bath and cooked it.

If you would like to come back to this idea later, you can pin the below image.

Examples of cotton clothing naturally dyed with 2 different techniques: shibori and eco-printing

Deciduous leaves eco-print

I’ve been busy testing a range of different leaves, using the eco-printing method described in my first ebook. Although that ebook focuses on eucalyptus leaves, which are still my favourite, the method works well for many other leaves. This is a sampler of mixed deciduous leaves: oak, blackberry, cotinus (smokebush) and two types of maple. I am going to be compiling all of my tests into a new mini-ebook, a guide to different leaves that print well. It will cover a mix of native Australian and foreign leaves, focussing on those that grow in temperate climates. I hope that this will help readers who don’t live surrounded by eucalyptus trees, or who just want to try new leaves.

Eco-printing with maple leaves

Maple leaves are high in tannins and so are well-suited to the eco-print process. Tannins help natural dyes bond to fabric and often also impart colour. Tannin levels increase over the growing season. So maple leaves picked in autumn will print more vividly than those picked in spring.

The different sides of maple leaves produce quite different effects. I like the delicate details of the sky-facing side of the leaves.

But the earth-facing side will print the most colour and be more colourfast.

These samples were printed with the method described in my ebook. I soaked the leaves for a few months to get rid of excess tannins, which bleed when combined with the iron mordant. The soaking process helps produce clear, crisp prints.



Good leaves to use for eco-printing: experiment two

I get asked a lot if the method I described in my ebook will work for non-eucalypts. These samplers are a good example of the results you can get using different types of leaves. Following on from the first experiment I documented, these leaves were left to soak for about 2 months before I used them, and it really made a difference! Some of the leaves printed better than others, but I really enjoyed seeing how so many different types of leaves, some native to Australia and some introduced species, can produce such clear and beautiful prints.

I sandwiched the leaves between two different pieces of cotton, to observe the difference in the prints produced from each side of each leaf:

Green eco-printed leaves

These prints are of the ‘sky-facing side’ of the leaves (where applicable). Most produced a lot of colour, and the leaf outlines and veins are crisp and clear. They are printed onto a yellow woven cotton, which has created beautiful green hues for many of the leaves, in contrast with the bluer prints below.

These prints are of the ‘earth-facing side’ of each leaf, on a white stretch cotton. Some still printed very clearly, especially the maple, oak and blackberry leaves, while others produced only faint outlines.
