We have (had) a very old bath towel that was shredding along the sides beyond the ability of a serge foot to fix. We only have 2 hand towels so I decided to turn the offending bath towel into a hand towel.I took a hand towel and laid it over the larger towel to get an idea of the appropriate size. I cut, forgetting to leave a seam allowance along the bottom, but no big deal. I folder over each raw edge with the idea that it would be 1/4 inch, but it turned into 1/2 inch. I ironed it in place then used a tight zig zag stitch to sew over the raw edge. I added a blue ribbon along the bottom of my new towel with Stitch Witchery tape and an iron since sewing that sucker on would have been the bane of my existence for the day.
