Teen, MadQuilter explained the process, but the crumb flimsy is mine. These blocks are 12". The sashing & cornerstones are 2". The crumb border is 4", also the blue outside border and cornerstones. The quilt is 6 x7 blocks and finishes at 94x116. (The quilt top is folded in fourths) I did not use foundation papers. When I started crumb work, I had two sizes going, 6" & 12". I finished the 6" flimsy, i did sew some 12 " blocks with four 6" blocks together to make 12" blocks for this quilt since I had no plans for another 6" crumb block quilt. Also, one, just one, block is 6", and double framed, you can see it on the left. I was getting REAL tired of crumb work.
