Make a girls nightgown from a pillow case...My crafty mom has made my girls lots of these and they prefer to wear them over any other pj!!!
Here it is - a tutorial for a girls nightgown - a free pattern for a 4T is included, but this is a really loose tutorial that assumes many basic techniques (pattern drafting from existing clothing for sizes other than 4T, gathering, finishing seams)
Pillowcase nightgowns using stretch elastic. Love! Dec 2012: I made ten of these, five for each of my girls, for Christmas. They love them!
