Sun Dyeing

I was reading a blog a couple of weeks ago with some scepticism. With the benefit of hindsight I concede my scepticism was a little unfair. The blogger in question had posted about sun dyeing and said that you don't need to buy those expensive photo-sensitive fabric dyes / paints, any old fabric paint will do. My initial reaction was, if any old fabric paint will do why is there a market for those expensive photo-sensitive paints? Too good to be true right?

The scientist in me made me set my scepticism to one side long enough to perform a little experiment. We all want to save our pennies to spend on more textile toys don't we??

Materials:

• Light coloured cotton based fabric (I expect silk will work too but synthetics possibly not - those are experiments for another day :) )
• A pad of newspaper or a large box (I used a plastic under-bed storage box)
• Masking tape
• A spray bottle filled with water
• Fabric paints (I used Setasilk (iron-fix) silk paint and acrylic paint mixed 50:50 with textile medium). If you don't plan to wash your fabric you can replace the textile medium with water.
• Large brushes (I used the foam type)
• Resists - I used leaves but anything that will lie flat on the fabric and block the light all work well. Paper cut outs and opaque stencils work well.

This is what I did:

• Stretch your fabric over a box or a pad of newspaper with masking tape
• Spray with water until evenly wet, allow the water to disperse while you gather some leaves or other objects to create a resist.
• Working quickly, cover your fabric with fabric paint and lay out your resists, ensure they are as flat as possible to the surface of the fabric.
• Leave in a sunny spot for 2 hours (beware of breezes blowing all your resists away if you put your box outside - I left mine in front of a south facing window).
• The hardest part is resisting the urge to lift the leaves to see what is happening underneath ;)
• Remove the leaves / resists and iron for several minutes to heat fix.

Sitting in the sun catching some rays, the pink and blue on the left is the Setasilk paint and on the right is red acrylic paint mixed with textile medium.

I think I applied the acrylic paint (on the right) too thickly, hence the effect is not so noticeable. In the areas where the paint is a little thinner the leaves are paler.

A second attempt with a lighter coating of acrylic paint. I also sprinkled a few grains of rock salt in the bottom right to see what effect that would have:

After 2 hours on a sunny windowsill:

Close up of the salt effect, it appears to have concentrated the paint under the grain and drawn the paint from the surrounding area:

Have you done any sun dyeing? What paints / fabrics did you use?
