When I had my shoulder(s) done (3 times) I spent a lot of time looking at patterns and magazines and planning out some of the quilts that I wanted to make.
Last Christmas, with my arm in a sling I was able to do some sewing. I did all my cutting before surgery, even used a bali pop that I had won, and with my (right) arm in the sling I could still feed fabrics into my sewing machine. I have a great sewing desk and it was the perfect height that my hand was at to be able to feed into the machine.
Take care though, you do not want to overdo it!!!!!
