I finally got the courage to pull out my sewing machine and sew my daughters a skirt each.
Pattern used was New Look A6258 by Simplicity.
|Skirt D from pattern|
|Skirt C from pattern|
Since I had never made an elastic casing before, I found this wonderful video by Charisse Eaves to use as reference.
My daughters were so excited about their skirts, that they wore them as soon as they were completed.
