I just finished sewing this blouse today. I was puzzled by the edges of the sleeve pieces at the underarm. Where I would expect to see a corner, it appears to have been cut off at an angle. I couldn't figure out for sure how I was supposed to line that up with the blouse. I just sort of winged it and I think it came out OK, but just wondering why it seemed funny to me. Any one else notice this? Liesl, can you explain?
