Oh my! First off, your quilt tops are beautiful and I am in love with #1 with the HSTs. I have torn both rotator cuffs, no spectacular injury like yours, just daily wear and tear from carrying a heavy leather purse for years (I only use quilted bags now) and probably taking exercise bras on and off daily for many years). I just had surgery on my right shoulder (I'm right handed) 1 1/2 weeks ago. I am already going stir crazy and chomping at the bit for when I can sew again. Everyone's comments have been very helpful to know that it will eventually end. I finally got to sleep in my bed two nights ago, although with the robo-sling it feels like trying to sleep on a camel with two humps.
Good luck with your recovery, and when I'm allowed to piece maybe I will make an HST quilt top like yours. We can start a group called Rotator Cuff Recovery Quilts, lol. Another thing, it sure would be nice if the surgeons used colored thread for those stitches. The black looks positively ghastly!
