Love ice dyed fabrics! Its been a while since I have done some, so here I go.
Basically, you need to soak fabric in a mixture of water and soda ash, then I like to hang it for a while so it dries to dampness; ie. not drippy wet. You need a set up that keeps the fabric separate from the ice water as it melts. I had the bright idea here to use hardware cloth. Then arrange the fabric on the wire base, cover with ice and then sprinkle with your dyes. Plan it or just go for it. This is a go for it, you can plainly see the dyes still powdery in some places in this shot.
About an hour later, evening is coming on strong. Dye is seeping down into the fabric.
Flash photo after dark. I am leaving it in place over night.... then we will see what we have!
I have always been an artist and with art quilts I have found a way to combine my two loves of painting and textiles.
