That sucks! I did that with one of my pairs of overalls. Except I didn't figure it out till I was already on the LEGS!!! I was not tipping all that out obviously, so I had to pick out 3 rows of stitches, try not to get lost in the half linen stitch, and then make it backwards. I did a pretty good job. It was really hard though. Learned my lesson!
Glad I am not the only one, and even more glad that I didn't get that far before I realized!
