No I didn't quilt make that mistake but made a whopper of one and didn't catch it till I had it on the frame, had quilted all around the block excluding the block in error. Had to frog all around the block, turn it correctly and then hand stitch it back to the quilt. It was not easy and I'm sure I swore under my breath about how stupid of a mistake that was. Like how didn't I see that before it was put on the frame??????? Oh well, its fixed and I now find if I take a photo of the quilt and view it on the PC screen I can see the mistakes easier than just looking at it on the design wall. Don't know why but it just works better for me that way. Surely don't want to go thru that again.
