I've been trying to figure out a color scheme. I've thought of primary colors in all shades. I don't have much of that in my stash, so maybe I'll look through my fabric and see if any color calls out to me.
I do have some fabric I absolutely love, but not sure if it would look good for pony blocks. It is some burnt orange, brick red, green, gold and rust. Hmmm.
It will help to get the book first and look at the blocks and then decide.
