Yes, summer dies sometime in September but summer is a great time for dyeing. I finally mixed up the three dyes I have (those pictured above), soaked some fabrics in soda ash and did some tying, twisting and clamping, then squirted on some colour ....
The two above were old white pillow cases. Below are parts of a white cotton shirt I made many years ago. I had added dimensional paint designs which of course remained after dyeing.
Above, some scrap fabrics. The green one had been used in paint clean-up so shows a few touches of stains but it still has lots of potential. Below is an old tea towel that used to be white.
And my favorite is another clean-up rag but the few stains are quite ok with me. I doubt I'll even cut around them when I get to using this piece.
