Pam has sold lots of her stuff on her hyena cart- you can check her listings to see lots of awesome stuff!

I didn't let my stuff dry, but it wasn't dripping either. Not sure if it was supposed to be dry though? It worked for me, lol.

As for colors- I wouldn't do colors that don't work together- not a lot of help, I know, but if you mixed it and it would make an ugly mess of brown, don't do it together.

The dharma page says how much dye to use per bottle. A little goes a long way with this method I've found!
