I don't know the answer to your question, but wanted to thank you for posting it. I have RA and the suggestions/comments of those who've posted are really encouraging. I, too, just do my rotary cutting on days that I can. Some days I can't hold anything and small items fall out of my right hand because my fingers don't close all the way. Nice to know others have found ways to adjust and still be able to quilt. I'd hate to have to give it up.
