Linda, you might mean the challenge one from 10 years ago or so? That pattern was designed by a lady from Scandinavia I think, and used a rubber stamp for marking the pieces for cutting and sewing lines. Way cute, but the rubber stamp kit was quite expensive, and the pattern turned out to be metric.
I switched fairly quickly to a similar sized paper pieced pattern found freely on the web, the blocks were 3" finished. I made them for years
I finally used them in a kit I got from a member here on the board in m y own setting. This is one of my favorite quilts I've ever made.
I just watched the MSQS you tube, their block comes out 4X6" finished. They are all good for scraps! I added corners to mine to make them finish at 6" like the blocks from the kit.
