This is my very first time ever trying to do them. I can't say that I love how they turned out but it was worth the try. The boys on the other hand really loved the experience.
I couldn't find the squeeze bottles so we used big droppers instead and pour the dyes in mason jars. Now, after doing, I have a better idea on how to mix the colors better so gradually change them and that I don't really need to soak them with the dye too much because the colors can bleed, but when you have two little guys helping and determined to use as much as possible, that's another story :)
