I had my hip replaced almost a year ago - I did a lot of embroidery and beading while I was immobilized. Since it's right before the holidays, maybe some handmade fabric holiday cards? You could do them all sorts of ways; embroidered, pieced, appliqued, beaded...lots of variety possible there. Prep them ahead of time.....just sandwich some stiff fusible in between fabric and cut and crease to make them card size and you have a good base to start with.
