Marbling on new tray

DH's tray works like a dream - though I had some issues with the day being very windy, not good for flat dyeing large pieces. I did not cure this for very long, as the turquoise dye was running everywhere. I am going to trial using my intense blue for a change.

I have thought of a brilliant idea for using my tray with the shaving cream dye thing, but not getting the marbled/swirly look. Stay posted if things work out.
