If you want RIT I would suggest that you search the New Rit formula thread in the techniques sticky for "dye fairy". LoPan found a gal in Tx with a boatload of old Rit that she's selling cheap. I have no idea if she has anything left, I got 16 boxes from her
. Some of 'em have become favorite marbling/painting colors, evening blue, aquamarine, and amethyst to name a few.
