I'm interested in paints and what they do. Does any one of you fabu ladies use them either MAC or HIP? Thoughts? Rite-Aid has all the HIP stuff BOGO free this week so I'm going to go up there after work and pic up 2 or 4 to play around with. Also, how do you use them? Which brush do you use for this? Is the HIP line even worth going to get?
