So much for tinting my U-Can-Do-3D canopy using the Rit dye method! I believe that I did everything right. The canopy "just wouldn't take". I keep large "pieces" of previous canopies which I use to experiment on. A Top Flite canopy piece and a Goldberg piece. They changed beautifully - an very quick! The UCD canopy just tinted a little after several hours.
