Oh yes, have done this many times. I found that taking a picture of the quilt all laid out is very helpful. Especially with the digital camera. I download the picture on my computer and the mistakes just jump out at me. For some reason, they are easier to spot in a picture. It works for me. But must add my last quilt ended up with 3 blocks upsidedown. I still don't know how that happened. Those darn imps again!!
