Yes, I finished a quilt recently that when put together the blocks made a diagonal pattern. I had noticed and changed a couple mistakes..thought I had caught them all..quilted it..sent it to Alabama to GS..forgot to take a picture. So he wrapped it around himself and someone photographed him & the quilt..when I got the picture on facebook it showed up very clearly..When I mentioned it no one else had noticed it.
I do try to get them right but most of mine may have something I didn't catch..I Don't like mistakes in my quilts but that happens..I did not show my quilts for a long time ...went to a big quilt show and found some ribbon winning quilts had a flaw in them..encourage me to try again..and not be so critical.
