Old Skirt to pattern off of
Fabric (1-2 yards depending on how big your old skirt is)
4) Now hem the bottom of the skirt by folding it under two times, pinning it, and sewing it. Make sure you don't sew the pieces together while doing this.
7) Once the elastic was pinned in I sewed underneath it. Make sure you are sewing the folds but not the elastic. Also make sure you pull the skirt tight and don't sew over any bumps. Then do your widest and longest zigzag stitch right over the elastic to hold it in place and stop it from flipping around.
You did it!
