You know something good's afoot when kids start coming up with their own hacks. From Bethany:
My oldest daughter actually came up with this one! She is really petite and we were given lots hand-me-down cotton pants, leggings, and other pants that lack belt loops. Since I’m not great at sewing I’ve struggled to find a way to keep her pants from falling down. She recently began to layer her clothes – multiple pants/shorts/skirts on all at the same time – and she realized that when she put bloomers on under her pants, the cotton “stuck” to the cotton and her pants no longer fell to the floor! Ahh ha! No sewing/stitching required! Creative girl she is!
