I too am a perfectionist..... made a jacob's Ladder quilt and as I was putting in my last bit of quilting, I noticed I had reversed a block...too late to switch it
Right now, I'm working on a Christmas Wall Hanging.I got the centre quilted and marked the first inside border and noticed I put all my corner pieces in wrong..so ripped it out...then marked it again and just as I started to quilt again...noticed that all my holly leaves were reversed!..ripped out again and re-marked....hope I haven't missed anything else...grrrrr
