I got my finger gloves (cots really as they just cover half the finger) from
http://www.fingergloves.com.
Not expensive, 6 times thicker than a latex glove, but still with plenty of feeling to even hold a sewing needle for applique if you don't have a lot of grip. The come in sizes, but I ordered 12 of the large (big hands) and got a free medium to try too. Obviously you could wear one on every finger/thumb, but I find just one or two on each hand is sufficient for quilting.
Re not expensive, 12 were $5.99, and if you share your experience, it's possible to get a gift packet.
Edit: just realised that it was in 2009 that I ordered the last lot, so perhaps the price might be a little different - sorry, I didn't mean to mislead. (Shows how long they last! LOL)
