Okay, I've once again turned into a living breathing Dharma commercial. Their dyes WORK!! Wonderfully!! Even the black!! (go with Jet Black - it's the truest deepest black they have.) I made a custom Jedi outfit for our FanForce Pres, and it turned out SO WELL. The cotton duck fabric we used (at his request) was originally that dark cream canvas color. I dyed it both midnight blue and black. Beautifully! I'll get a picture up here shortly so that you can see the results. Awesome stuff. I'm excited to start trying different dye techniques now. He's the guy on the far left in the blue and black Hee - believe it or not, that's from the same group of pics that Kirana_T linked to for her Picnic dress (which turned out FABULOUS, btw).
