Hey, I do this! Mine are more complicated though, panties are Very uncomfortable without a separate crotch piece. A seam rubbing in the tender bits is absolutely horrible.
I made this pair for my little sis'. There were tons more but I never took any pictures. I'm working on another set for a craft show though, I can post pictures when they're done.

These hold up well, they're about 4 years old in this picture (sorry no action shot, lol).
