I just had to do that! Luckily I was only half finished and it was a shall quilt. Some of the blocks have letters on them done in a sort of rope print. The other blocks are little cowgirls and cowboys. I had one of the letter blocks upside down. I know it would have driven me crazy on down the road, so I bit the bullet and frogged it! We are all guilty of that sin, once in a while!
