I know this doesn't look a whole lot different than the last design wall, but I do have 9 rows sewn together instead of the 2 last week. I haven't decided how many rows I'm going to make, but I have enough tumblers for 12 rows.
Using the accuquilt I figured one important rule to follow. Put a piece of paper between the fabric and the cutting mat. I had some tumblers that were 1/4" short, and when I re-cut them with the paper, were just right. I don't know exactly why some of them were mis-cut, but it seemed to be the lighter weight or loosely woven fabrics. Next time I cut, I'm going to use paper on each stack. It doesn't hurt anything and will insure that they come out just right. The white I'm using is Kona cotton, and when I cut the edge pieces there were short. The other stack was the pink/lavender one that looks striped. The Kona is kind of loosely woven and the lavender a light weight fabric. Perhaps if I had starched it would have been fine.
Anyway, just a little tip.
