i use roxanne thimble. when i first got it, it fitted well but due to climatic changes, my finger swelled up and I couldn't use it. I recently took it out and started using again and though it started off tight, as I started using it for 10-15min, my finger started to shrink inside the thimble making it very comfy. I would not say that it is a 100% perfect fit, but it doesn't drop off my finger at least. according to the company, if you are quilting ergonomically correct, your fingers will start to shrink alittle inside. would highly recommend roxanne thimble to anyone.
