This is an example of a figural thimble. I am not a huge fan of the figural thimble because they are basically not thimbles, but little hollow sculptures sold as thimbles because, of course, thimbles are the bestest thing in the whole world to collect.
This one is of Glinda, the Good Witch of the North. I loved Glinda when I was a little girl, though I never really understood why she didn't tell Dorothy right off about clicking her ruby slippers together to get home. Poor girl had go to all that bother with the flying monkeys and everything when she could have popped right back to Kansas easy as pie.
This "thimble" is pewter with pink and blue crystals, and available through myrose.com for $7.95. NO S/H fee to the U.S. (and some other countries)! YAY!
