Once I was making a friendship star quilt for a friend's baby and was in a hurry. I had the quilt top finished with the borders on when I showed it to my husband. His question was: are all the blocks supposed to look like stars? I had inverted the star points on 2 or 3 of them. In a fit of temper, I wadded up the top, tossed it to the floor and walked away. But as all quilters know, you have to come back, pick it up and make it work.....so there I was, ripping out the wrong blocks and re-doing them. My lesson learned was before I sew the finished blocks together, check them against the pattern to make certain I have it right....resewing a seam is never fun.
