I remember when buying a Roxanne thimble (have since switched to Thimblelady method), they had excellent instructions for fitting the thimble. I can't remember the method now, but if you go to Colonial Needle website and check out the Roxanne thimbles, you should find it. I believe I needed a set of round plastic finger sizers, which they also sold. I'm not familiar with the quilting method you mentioned, though, so I don't know if this fitting method would be applicable.
