Thank you all. PBPam, you could use the cream as your sashing and backing. If you want to do one block, just do a little research and find a block that is era appropriate.
Mine was a BOM and supposed to have 12 blocks set together with 12 1/12" uncut blocks of some other print. I felt like during the CW if they'd had a huge piece of one fabric to cut into twelve and a half inch blocks they would have made clothing out of it so I added blocks on my own and made mine the way I wanted it. There were blocks I wanted to try out so I just did them--the Fan, Carrie Nation, Cherokee Star, French Braid, Crazy Block, the one with the 1" blocks, and several others were just ones I threw in.
