I'm making my first quilt, a pinwheel table topper. I've finished the pinwheel blocks, and some are larger than others. Some of the blocks are larger at the bottom than the top, or vice versa, as well. Some of it is due to imperfect cuts, some to imperfect seams. It's all fractions of inches. Should I cut the blocks so that they're all the same size before sewing them together, or just go with it? I'm worried that at a certain point, I will wind up with an irreversibly not-square quilt. Thanks.
Also, if need be, I can post a pic of what I'm working on.
The first pic is of the overall project. I'm not decided on the color order, yet, but this gives you an idea. The yellow block in the middle needs to be completely redone for the start.
The second pic shows a block that isn't square. The top row is wider.
