Painted 9"x12" black construction paper that I used 150 grit sandpaper on to rough up the surface because I didn't think the regular paper would accept pastel well. Black is an interesting color to work on...you can still see it through the ice cream (but I figured it would show through) and it really made my colors POP more than I thought (I've mainly worked on white or cream papers before, so that's why I wanted a cheap way to try colored papers). Except for the pink not being as solid looking as I'd like, I'm actually pleased with it because for my skill level, it's good. :) I haven't sprayed a fixitive on it yet so I don't know if I could get the pink "more solid" by doing that or not. I think I need more peach.
