Don't beat yourself up over the woulda, coulda, shouldas. We all learn from our oopsies. I don't cut all the way from corner to corner around the blocks. To start sewing the blocks together I take my snips and cut the corners of 2 blocks and sew, more snipping and another block is added. More snipping....... hey, I get my exercise and my little brain doesn't get too addled. ;~)
