I am also a thumbnail quilter, I do not use thimbles of any kind. I have a very strong thumbnail and I quilt away from myself so turn the hoop often. For curves I go a little slower and take only one or two stitches at a time. I am in no hurry as hand quilting is my most favoured part of quilting.I tried all the thimbles and finger protectors etc but found it was like swimming fully dressed, I just had to work with my bare hands. I very seldom prick my finger, only once in a blue moon now.
