Glad my review was helpful. If you have any other questions, just PM me and I'll help you out.
I was thinking about showing a photo - but I don't think that would be very helpful to you. I use a size M (medium) - but since you can't see my finger that's not going to be much help either :(
Definitely shop around - if I recall there are places in the US and Canada that sell these thimbles.
My thoughts on these thimbles (the 2 I have) are that they will be my thimbles for life. Okay, maybe not life, but maybe the next 20 years. I hand quilt exclusively and while working full time I manage to complete 1 queen size quilt a year.
