Teen age and college girls really like the makeup bags and the jewelry rollups, especially those going to college. Also, they like the curling iron cases so they can put their curling irons in while still hot. Same type of cases could be made for hot rollers, too.
I've been making pillowcases for the younger ones (preteens) and backpaks for the little ones, especially the girls who love to carry their dolls around. I want to make a doll quilt for my DGD this year.
