I have a clear plastic extension table for my machine, and use one of silicone slip sheets with it and the rubber finger tips. I agree, the gloves are too hot and too difficult to try to grab the threads with the left hand when pulling up bobbin thread to the top. The rubber fingers are easy on and easy off, and grip very well.
Yes.....table height, feet flat, support for your back and arms at 90 degrees are very important for any FMQ. Remember, it's supposed to be fun. Put some good music on, and breathe.....and have a blast!
