After zigzagging the ends and in between the towels, they all went into the wash and dry.
I pressed and then cut and sewed up the hems for the extra piece which amounts to a square and the 6 towels for Grace.
For the last towel, I decided to try to use my serger with a 5/8" downturn feller to see how that would look.
I decided even though the edge is a bit rough, I liked that there was not any extra fabric for the fold over hem. If I do this again, I need at least 1.5" hem on each end so the fold over is still in the plain weave.
