Have started to hand quilt and have noticed places where the seams have come undone. I have already gone too far in the process to undo. Can I whip stitch the seams and hope for the best? Any other suggestions? Also have a place where there is a small cut in the block. A lesson to be learned is to check all seams/blocks before moving on to finish it. I have a lot of expense and time invested in it so would appreciate any suggestions to save this masterpiece. HA!!
