I learned to use a thimble by using underneith. Get an older thimble at the thrift store that is almost smooth around the top edge and flatten the top. Use the edge to help guide the needle. It works.
The spoon also works as it makes the pleat needed to form the stitch. I also use the inexpensive thimble that is depressed on the top. Save for the more expensive thimbles until later. The cheepies work as well. I would think the problem with the needle damaging the spoon as reported above is that a silverplated spoon might have been used which is a softer surface. Stainless steel would not damage. I find that the older thimble does not damage the needle either.
Harry - how far are you from Sturbridge. I teach hand quilting at Charlton Sewing Center.
