I would like to add a good Color Changing Silk routine. Something that could be used for both close-up and stand-up with an adjustment for the size of the silks being used for the venue. Smaller silks for close-up and larger silks for stand-up. Any and all suggestions are appreciated.

Clearly, there are several ways to achieve this - TT, dye tube, palmo, etc. But, I would recommend to determine WHY it is you want to change the color of a silk and then design a routine/technique on the most natural way to achieve your objective. Starting with method and backing into a plot is rarely a good or convincing strategy to convey a magical effect............
