The trick with rit is to heat it to between 130 and 140 this is a must do or the dye will not take on the canopy when you are done pour the dye into a plastic jug for use at a latter time. I have used the same batch to do four canopy's but each time you have to leave the piece you are dying in the mix a little longer works great but the heat is important the first time around I think it must activate the dye because if you don't cook it first it will not work.
