Color Cube by Sarah Renae Clark

I have. I have not crafted as much as I would've like to since I bought them, but the few times I have been able to use them I found them very helpful. I find they help me use colors I would not normally choose, and I have been pleased with the results.

I've seen Jennifer McGuire and Call Me Crafty Al use them on videos but don't have any experience myself.

I use them all the time for cardmaking. I'm terrible with color selection, so I find it quite a bit easier to make something pretty once the colors are chosen for me.

I mostly use mine sort of backwards. I make a lot of patterned paper-based cards, so I'll try to pull a color scheme out of the pattern, but then see if the cubes corroborate the choices.

This is kind of fitting because they were a gift from my kid who is now at college. Up until college, that kid was my second opinion on all such matters.
