some people with problems like yours use mouth controls I don't know if you could get one adapted to use your machine. My mother was diagnosed with MS when I was 3 months old and she ran a boarding house for many years till she retired at 65 years, she was one of the fortunate ones as she was in remision for most of her life we all tried very hard not to cause her stress as that would cause her to relapse and each time she relapsed she would end up with more dissability than before, she is now 97 and in a nursing home, my DH and I looked after her for 8 years after dad died and only put her into the nursing home after the house burnt down, I do wish you the best I don't physically know what you are going thru but after looking after mum for 8 years gives me some insite on things. I hope you find a solution so you can continue to quilt. my mum refused to give up to.
