Frolic is one of the BH mysteries I also didn't finish (along with both of my versions of Good Fortune). This post nudged me to get everything out and look it over.
I had not been pleased with my Frolic. I tend to get kind of obsessed with the paint chips and stick close to them, but after seeing other people's brighter looking Frolics -- speaking particularly of the dark reds I used -- I had entertained the idea of bringing in some brighter reds. But upon refreshing my memory, I see how hopelessly intertwined with same fabrics all of the block components are! I also remembered what fun I had working on it. I think those were the most intricate directions ever for a mystery, as far as same set components and setting things aside.
So I'm thinking I won't try to revise any of the blocks, but possibly can insert some brighter reds into borders.
