So far I've made two of these. Using original pattern, that one went to my MIL. (Too small for my liking even though I loved the material.) Made a little bigger second time, co-worker says, my daughter would love that, so handed it over. No matter, I still felt it wasn't big enough. Finally able to get interfacing yesterday, so will set about making another one tomorrow night.
I really like the looks of it, just need to get a size that works for me.
