Bonnie Hunter is holding a thimble talk linky-thing...for what it is worth here is my take on thimbles....
I was an off-again-on-again thimble user until I took an applique class with Pat Campbell. It is sort of uncomfortable I gripped. "Grow up and get used it" was her response (said with a very sweet but take no prisoners southern accent.) So during break I bought a very pretty solid silver thimble then tried to use it back in class. It still was awkward. Pat looked at the thimble and said, "it will look nice on shelf."
So she gave me a few pointers on thimbles that have served me well. First, put it on your finger and shake you hand. Not a wild "I'm being chased by zombie hand waving" but a bit more than a Queen of England wave. The thimble should stay on your finger. Second, the dimples on the top of the thimble should be deep. This is the part that will hold the end of the needle. This is even more important when I use the thimble hand quilting. Third, living here in the south it is very possible that I will need multiple size thimbles...just like there are rings I cannot wear in summer due to my hands swelling in the heat there are "season appropriate" thimbles too.
So my go-to thimble is the brass colored one with a magnetic top. I've had it for ages. It says made in England on the side. The magnet is particularly helpful when I am using tiny needles. I use this primarily for hand piecing and applique. The zinc thimble next to it is another all-around thimble. It is slightly flattened so fits my finger perfectly. I use this often on my right hand when I am hand-quilting.
My favorite right hand thimble for hand quilting is this very inexpensive Dritz Slip-stop thimble. I have it in several sizes. In addition to deep dimples there is a ridge on the outside to hold the needle in as I rock it.
If you find a thimble you really like buy six. I'm not just saying that because I own cats who love to play with thimbles. Thimbles have a way of traveling. They are left behind in airplanes, summer houses, and anywhere else you find a moment to stitch. Unfortunately most non-quilters don't understand the desperation in your voice when you call and ask if you left your thimble there. Even if you say it is your favorite thimble in the world and they aren't selling them anymore and you need to finish this quilt for ____ (fill in the blank.) Sure the person on the other side of the line will tell you they will look but really, you expect them to understand your need for a thimble? On second thought...buy a dozen.
