I just get them from Dharma Trading Co. Homepage . The only thing they require is a tiny bit of plain vinegar (that is the "acid"). Actually, depending on how you use them, you may not even need vinegar.

You can use them in a washing machine on hottest setting (doesn't give the absolute deepest/brightest colors but pretty good.

You can dye in a pot simmered on the stove (best for solid dying).

Or you can sprinkle, drizzle, dip etc. and then microwave for a couple of minutes.

Or you can use a steamer, but I don't have one.

I started out using Procion dyes but Procion dyes are very sensitive to tap water chemistry, pH, salt concentrations, etc. Blue reacts very slowly with silk, so everything shifts away from blue. I also found them impossible to create predictable, reproduceable results.
