The top is finished and I like it so much better than the original.
Now the tip, which you may already know, but was new to me.
I knew the bias cut triangles were going to be a problem, especially the larger ones, so I spritzed them lightly with spray starch. (That's not the tip for you, I already knew that would help prevent stretching.) I had a problem with the spray can and soaked one of them. Afterward, I noticed that it shrank as it dried but ironing it straightened it out. Originally, the strips were 7 inches, which was actually good for me because after I sewed the pieces into 12 inch blocks, there was enough excess to square them up nicely. Still, when I put the rows together, I found that one was a half inch longer. It had two of the large triangles in it and they had stretched. I pinned them together, matching the seams and spaced out the "ruffle" of the stretched triangles and pinned them. Then I saturated it with the spray starch. When it dried, no more "ruffles" and it sewed together perfectly. After ironing, the starch relaxed and it looked fine.
