The worst thing I did was sew a block together wrong. Not too bad you might think. Just take it apart and resew it, right? Well it's a little more difficult, when you don't notice until the quilt is already quilted and ready for the binding. My mom's quilt still has the error in it to this day. She's never said anything. So I don't think she's even noticed. But it's pretty obvious, if you look at it. :lol: :lol: :lol:
