To finish the skirt - easily and adding texture - try the lettuce hem. When working on the bias it is especially easy to make a natural frill to the hem. Choose the smallest zigzag and length of about 1.
Begin sewing, keeping the fabric pulled taunt both in front and behind the presser foot. Voila! A fast hem, but one that adds to your skirt. I chose a shiny red to just give it a little pop!
