Maybe she could buy and use the finger cots that physicians use for examinations. I buy mine at a Walgreens or a medical supply store--don't buy the ones sold at Quilt Shows as they put only 5 or 6 in a bag and charge you big bucks. They roll onto your finger and each one lasts a long time. I actually give my beginning students one to use to pull their needle through the hand quilting. Of course, the girls laugh uproariously when I pass them out.
They do come in different sizes too. Oh, I have also found them in large quantities in the hospital pharmacy.
