Well, like I said, I Dyed mine with a half a pack of "Dark Brown" powdered, RIT dye. I heated a pot of water. (about 1.5 lt. of water) until it boiled. I put in the dye (the half pack that I mentioned.) And stirred until it was completely dissolved.
I added the ribbon, and stirred it for 25 minutes.
I took it out, and put it in really cold water in the sink (because, I live in an apartment, and I don't have a washing machine) a squeezed, and stroked the excess day out of the ribbon. Then I moved it to a clean pot of more cold water, and continued to to clean the excess dye out, and then I moved it to one more pot, of cold water, to make sure I got all of the excess out. Then I hung them up to dry. It been a week, and they are still green.
Now, If I pout them through the wash, or drier, that may change, but for now, they are green. I mean, I don't consider it a forest green, or neon green, they are a brown-ish-green, but very, clearly green. (again, green enough, that may girlfriend said, "those are dark green, and light green strips.)
It's no big deal. The ribbon is cheep, and I like dying stuff, so I don't mind giving it another try, when my next batch of ribbon gets here, and I can buy some fresh dye. (really don't want to try it with the other half of the pack I have, after what happened this time. )
