Great quilt, love the way you used the colors. I;m sure he is going to love it.
Good luck on your surgery, am in the first weeks of my second knee replacement. Thank goodness I have only two knees. The secret to recovery is doing your physical therepy and continuing the exercises. I made a scrappy couch throw before my surgery and have hand quilted it during my recovery period. Helps pass a lot of time and can still do what you love.
My prayers will be with you, it is a painful process and healing is slow.
Let us know how you are doing as you go along.
