Don't feel too badly, Ive been sewing for over 50 years, and the other day I not only sewed on both armhole facings of a shirt on the wrong side, I clipped the curves and double stitched them both. I have learned to laugh at myself, but I wont repeat what I called myself. I just got over it and ripped it all out and re did it all. It looks great now and I'm very pleased with the results. Will I ever do anything that dumb again?......probably so, but I hope not soon!! Hang in there. Remember, Babe Ruth also held the record for most strike outs!!
