Went to a couple of estates sales recently , but did not find a lot. First one advertised a lot of costume jewelry, and yes there was a lot. However the prices were on the high side, and none of it was marked so you had to ask the price (don't like having to do that). Told the sale worker what I was looking for to repurpose, and she said "we have had several people in today that does the same thing". Looked around at the furniture, and accessories (even tho was not in the market for any), and there were several antique pieces. An antique baby cradle on rockers for $650 was getting a lot of attention, but no one seemed interested in buying. Anyway, no purchases made there. Ran a couple of errands and stopped at another estate sale. Very little jewelry, but priced more reasonable, so did get these pieces to repurpose. The earrings have the old screw on backs.
