Deedles, I had a knee replacement a little over a year ago. I didn't feel like, or have time for much for the first 3 weeks, between therapy, ice packs, resting, etc. But you might have some hand work available, as each person is different. However, it was only 2 months after surgery and I attended Machine Quilters Showcase in Kansas City for 3 days, took classes, walked the vendors mall and enjoyed the quilts. I didn't do much in the evenings but rest and put the leg up, but I was able to go and enjoy it. And that was my goal. You just need to keep being active and moving around, sewing will not be a problem. Good luck with the surgery.
