If baking soda does not remove the smell from the celluloid, you might take the piece to a place like Michaels … their frame shop should be able to cut a new piece of material (maybe heavy template plastic) to the right shape.
"Are your museum specimen pearls drilled?
"
that was at the end of her post, and I thought it was hysterical because... Well, I don't know. Things've changed so much in pearls since 2009.
I just came across an old post where someone said they were going to put on their very large pearls - and those pearls were 7mm! :-o. Newer pearl buyers think that's a very ingenue-ish size. These little white pearls of mine are from the olden days, the early Chinese rejects, veeeeerrrry small.
...Ok, ok, I've got it! Maybe.
It's funny because it's a reference to our na?vet?, and the learning curve we went through as the stars in our eyes and gambling urge blinded us,
and early unscrupulous sellers on ebay had their way with us.
LOL, and they surely did have their way with us, at least once! Some of us twice, maybe three times.
or perhaps a time or two more (cough, cough)
