I made some summer nightgowns for some little sweeties... I used some fabric I had in my stash (thanks, Aunt Cheryl) and used this pillowcase dress tutorial here. It was super easy and the girls just loved the feminine feel of their new nighties.
For the arm holes, I just used bias tape to finish the edge (this also serves as the ties). I put rick rack at the bottom of this one. This one already had a lovely edge to it. I definitely recommend this pattern to anyone with a little girl who has to sleep through hot summer nights with no air conditioning... I think I may make a couple more today.
