Hoping the finger surgery goes well for you, Terri. Follow dr.s orders! You can peruse patterns and surf online while you can't sew. Try Pinterest. You'll be there for days!
Joan, if cutting is making your should ache, please change your rotary blade, and possibly your mat! You can flip your mat over and use the smooth backside like a new mat, minus the lines. (You can get your lines from your ruler.) It sounds like you are having to press down too hard on your cutter. That will bother your shoulder. Maybe that's what's wrong with mine!
