I have lots of aqua and aqua/green. I also think I can come up with the coral or warmy pinky. I don't have much peach. And neutrals I've been collecting. What I'm really missing in my stash is brown. I only have one brown that I would consider a dark. I do have lots of charcoal, but with the other colors being on the 'warm' side, I'm afraid that charcoal will be too cool, especially with warm neutrals. I bought a couple cream on cream neutrals last week that I was hoping to use in the project. I need to make some fabric pulls and play with it. But I'm thinking I'll need to buy some more brown.
I'm planning on make a small version so 1/2 of the units.
