How long should I leave them in the hot mix? I ask as errrrr.... they are in now lol^^^^ like he said, i wouldnt use a good pot, ive always just used a plastic bucket.
Wrap it up in old blankets or polistyreen (sp?) to insulate it, fill it with boiing water and then just keep topping it up every so often.
Make sure you rinse and scrub it after your done to get all excess dye off otherwise you might get it somewhere you dont want it!
