I am right handed and only handquilt in a hoop. My left hand is underneath and I feel for the needle to scrape my index finger. When my index finger gets sore, I switch to my middle finger. Eventually I build up a callous. I have to feel the needle but many can do it with a thimble on their underneath finger. There is also a tool called an "Aunt Becky" that can assist with this and if you want to go real old school, you can use a spoon. I am fine with using my finger.
I would recommend choosing a different batting in the future. W&N is an absolute bear to handquilt and while you can, I think you will find other battings much more cooperative and easier to needle. W&N is fine for machine quilting. If you prefer 100% cotton, spring for Quilters Dream or Mountain Mist Blue Ribbon. You will notice an improvement in ease of stitching and getting smaller stitches immediately.
