Okay--let's see if I can explain this clearly.
I am making a stacked coin quilt of flannel. The coins will finish at 4x10" and will have sashing between each of the five columns. The columns will be 18 coins each. I'm a bit concerned about the possible stretching that might result from sewing all 18 coins together before sashing (a few of the flannels are thicker than others and the resultant weight of the columns might cause them to go wonky in that long a strip).
My idea is this: sew 6 coins together and sash the side of that piece, then sew 6 more for the second column, sash, and work horizontally across the quilt. I would then have the top third of the quilt together. Repeat for the middle third, then the final third. Finally, attach these together to form the complete quilt.
Am I missing something that would make this unworkable? It seems to work in my head, but I'm afraid I'm missing something that would create a problem. Any thoughts, ideas, or suggestions would be great.
