Recent project using McCall's pattern 6066. It's a youth skirt for girls. I tried the F cut and found it to be simple to follow, not difficult, and easy to modify. This skirt is basically a circle skirt and it great for twirling little dancers.
I used an IKEA home dec fabric (the vegetable pattern) and a simple gingham in tablecloth check size. The piping along the bottom of the skirt is bias tape I made from scraps.
