This is probably one of those things that many quilters know but jut now I had an "ah" moment.
I had been cutting strips with the June Tailor Shape Cut and had laid that aside to go back to working on a star quilt. Just had started to square up the first block when I saw the Shape Cut sitting right there.
aligned the 45 deg. Line with the seam down the middle of my block. Easiest squaring up I've done in a long time. My eyes & hands just don't work like they did 30 years ago
hope this idea can help some other "granny"
