I understand! Last year, I planned to make monogrammed 'hoodies' for my grand son and his girlfriend. Good thing that I decided to practice on one of mine! Did the whole floral embellished initial upside down!
Last week, I was sewing 3 3/8" squares of patriotic fabric left from QOV together for hst blocks. Did a pile, chain pieced. Cut them in half. Started pressing, only to realize that I had sewn 3 squares together instead of 2. Not once, but two times!
