I cut down the side of my forefinger about three years ago and had 8 stitches. There was a quilt shop at a show a couple months later that was selling some sort of guard that went on the ruler. My aunt was determined I needed it but I held out. I am very careful now and have not cut my fingers while moving but have managed to touch my knuckle to the blade a couple of times recently.
i am positive there is some sort of protective handwear. You just need to try some and see what works best for you.
