I was working on an EC sleeper pattern back in 2004... for obvious reasons I never completed it.
I used a basic baby sleeper pattern, but altered it to resemble those "butt-flap" sleepers. The ones most babies in old bugs bunny cartoons wear...
Only 2-3 snaps across the butt instead of a dozen all down the crotch! Very handy. If anyone wants my notes to work from, let me know.
