Simple pull-on pants were just the thing -- only I had to design the pattern myself and that took a bit of trial and error.
Knowing that I experimented first with a flannel rag. It became PJs because even the first effort didn't turn out too bad. Yay!
I've fiddled with the pattern a bit more and come up with an even better fit, which will debut when the Soso faceplate arrives all freshly "faceupped" from Ban's Boutique.
