I have a little mad idea, and need your thoughts. This food colouring dye thing has my cogs turning in the background, and I am playing with the idea of doing some recolouring on some heavy woven wool fabric, but it is too big a piece to microwave. Do you think using a heat gun or a blowdrier - judiciously spaced away from the surface - would heat set the dye colour? I'm thinking blues and greens...
