Eco Printing on Fabric: Beginners Guide

3 Shares

Hi Creative Mamas! Welcome to this Beginner’s Guide to Eco Printing on Fabric. As you probably know by now I absolutely love playing around with natural dyes to create botanical prints and beautiful natural colors.

Eco printing techniques allow us to take the knowledge we have on natural dyeing and apply it in a very creative and experimental way.

You can combine eco prints from leaves and flowers with iron blankets, color blankets, solar power dyeing, natural dyeing... the sky is the limit!

In this post I want to introduce you to the world of eco printing on fabric and I want to share with you what is actually possible through experimenting and getting creative with this method of eco dyeing.

Eco printing on fabric

Botanical prints on fabric are created in a similar way as the botanical prints on paper. However, when eco printing on fabric there are a few things that are important to note:

  • The prints must not wash away
  • The prints need to be colorfast and not fade away when exposed to the sun
  • The fabric needs to last (this means being careful with the use of iron and any other substance that may deteriorate the fiber and damage it)

Eco printing on natural fibers

As with natural dyeing, you must always use natural fibers such as:

  • 100% cotton
  • 100% linen
  • 100% silk
  • 100% wool
  • 100% leather
  • any mixed fiber blend (30%silk, 70%cotton)

In order to confirm if your fibers are 100% natural you can perform a burn test. It’s super quick and easy!

Silk, wool and leather are protein fibers and need to be mordanted and scoured in a different way than cotton and linen which are cellulose fibers.

Mordants in eco printing

For protein fibers I only use Alum Sulphate as a mordant. It’s very eco friendly and gives the best results as far as I am concerned.

For cellulose fibers I only use Alum Acetate in combination with Soda Ash. This is a longer process than with protein fibers but it will give you the best results.

You can read all about how I use mordants in my natural practice here.

Plant material

Choosing the right leaves and flowers is the most important part of getting started with eco printing.

If you are printing with flowers that have no dye in them it will be a waste of time. The same goes for leaves.

Some leaves have beautiful dye qualities and they are high in tannins which make them perfect for eco printing. Others will not provide any prints at all.

Leaves and flowers

I grow my own coreopsis and dyer’s chamomiles at home. These flowers deliver the most bright yellow prints ever! I just love printing with them.

For leaves I tend to go for eucalyptus, maple and liquidambars. These is what its readily available to me in my environment but check out the list of 30 plants you can choose from.

Eco printing on silk fabric

I get the best eco prints when I am using silk. This fiber takes the natural dyes beautifully and if you scour and mordant the fabric correctly you will achieve bright and shiny prints.

The photo below shows an example of a thin silk habotai printed using coreopsis flowers and eucalyptus leaves from New Zealand (there are many different varieties of eucalyptus and they all yield different tones and colors)

Eco printing on cotton fabric

The photo below shows a print made on cotton fabric using liquidambar leaves and dyer’s chamomile flowers. I used an iron dip for this print so there is a bit of black and the flowers turned from yellow to green.

However, you can easily appreciate how the prints are a bit more muted and less bright than the one obtained in silk.

Eco printing on wool fabric

I also love using wool fabric to print with. I like to upcycle old woolen blankets which I usually get from thrift stores.

The photo below illustrates an old woolen blanket that was printed in one of my live eco printing workshops using avocado leaves alone.

As you can see the texture of the fabric provides an interesting canvas for the print.

Below is an experiment that I did by bundle dyeing wool fabric. I used rusty nails and objects as well as an avocado dye bath instead of the usual steam process.

Eco printing with iron blanket

Using an iron blanket is a great way to obtain different effects from the same plants. Basically a blanket is a carrier.

The idea is that you lay a piece of fabric. You then place your plant material on top of it. Finally you place another piece of fabric which is carrying the iron and you place it on top.

The blanket or carrier will transfer its color or modifier quality during the steaming process.

When working with iron, I actually prefer using it as a dip. The photo below shows a silk scarf printed with a sunflower and an iron dip.

Eco printing with color blankets

Color blankets follow the same process as the iron blankets. The only difference is that rather than transferring the color modifying qualities of iron they transfer color.

I print with color blankets using natural dyes and the results are amazing!!!!

The photo below shows a print created using a cochineal color blanket.

The photo below illustrates the results that can be achieved by combining blankets and dips.

Natural dyes and eco print

Over the last couple of years I have developed my own signature way of eco printing by combining it with what I love most: Natural Dyeing.

I created a process of mixed media that allows me to combine traditional natural dyeing methods with solar power dyeing and eco printing.

This is probably one of my favorite pieces but when you work with mixed media there is no limit to what you can achieve 🙂

Fresh leaves or dry leaves?

I use both, dry and fresh leaves and flowers. I know that some printers recommend only using fresh but in my experience I always get good results with both.

If you like to collect leaves for later use, I recommend that you keep them inside book so that they dry flat.

The other thing to consider is to hydrate your leaves and flowers just before using them for printing. I use clear water and that gives me the best results.

The most important thing in eco printing is choosing the right plants to work with so make sure you download your FREE plants list to get you started in eco printing straight away 🙂
