I'll try to take some in a bit, but basically I sewed together two HST, one half is of the precut fabric, one half is ones I cut myself. Some of them are exactly the size and shape they should be (square 5.5"), but some are longer on one side or shorter, so not completely square.
I will sew four together to make a pinwheel, and am wondering whether I need to square the dozens of pieces now, or the larger pinwheel blocks later?
