Yes, this has happened to me--but it didn't happen when I was aware of "computer corrections available to any quilter nowadays"--so I spent several days agonizing over it, scrapping the whole mess, and it's scattered among all my UFO stuff in my sewing room--probably bound for one of my sister's yard sales in 2013.....if I can find someone to help me do the down-sizing effort that is so desperately needed out there......by "out there" read that my sewing room is a building all to itself about 50 yards behind my house....
