These lovelies were dyed in a tray that I used to use for marbling, made by my brother who was a sheet metal worker. Thanks John!
And then some fire red...you can swish it around, tip the tray to mix or just leave it alone. Then I lay a piece of fabric (this is a fat-quarter tray) over the dye and move it, pat it, whatever I need to do to totally soak the piece.
They sit out in the sun for a few hours and then I throw them all into a cold wash with synthrapol and then 3 or 4 hot washes...till the water runs clear. The result is the fabric in the first picture.
I put at least a few colors in each time, so there is nice color-play in the finished pieces. Mushing it up accordion-style makes for nice striations with the colors.
