When I dye ribbon with reinkers, I do it in the bathroom sink - just splash some water onto the surface of the sink so that it's wet, then drop reinkers onto the porcelain, and toss my ribbon around until I like the color of it. It's probably unconventional, but it works, and it's easy to rinse the extra dye down the drain.

then by all means paint, and that voice will be silenced.
