I have decided that anything I cut is square and good enough ! If I cut it and it's the proportions I want, it's good. Too many fabrics are so off square that I just don't care anymore, and it doesn't matter at all.It seems that the last 6 or 7 years I get more and more fabric, way, way off straight of grain....I just don't bother with it anymore. When I cut strips. squares, triangles, whatever, what matters the most is accurate cutting and accurate piecing. The only time I worry is is with blocks set on point, then the outside triangles can give you a time, but I just staystitch bias triangles, then it's not a problem. Don't get bogged down with the minutia...if you cut a 2" square and sew it to another 2" square, if your cuts are accurate, and your 1/4" is good..then it's all good!!!!!
