Welcome back!!!! So good to hear that you are doing well. I can understand the bored thing with my hand in a cast and not able to grip anything. Makes it really hard to hold a pin let alone a pencil or even feed myself.
Hang in there....it gets better. Had my shoulder done a few years back and couldn't do anything then either...but it gets better. Can't wait to see the wonderful creations that you come up with when you get back to sewing. Hugs and well wishes and lots of prayers.
