In my 40 years of sewing I used a thimble on the rarest occasions, mostly to push a sewing needle through several layers of thick fabric. I just started hand quilting my first quilt 2 weeks ago and I had one that fit me, so I started using it. Within minutes I discovered it was either completely worn out or cheap junk (which I think it is). Stopped using it and used my finger to rock and push. Poked myself deeply, twice in the same spot, and ran to the store. The only one I could find that would fit somewhat was the Collins Safety Thimble, size Large.
I used it on my middle finger to push the needle through, but had to take it off each time I took a stitch, because I couldn't feel my needle! Finally after 2-3 days of forcing myself to wear it, I am comfortable with it and it contributes greatly to the quality of the work!! I don't use a thimble underneath, haven't had any need to as of yet, as I rarely touch the point.
I would love to know where to purchase thimbles for mens hands! It's very hard to find large thimbles. I'm don't have big hands, but nonetheless, I have a man's hand.
