I see depression glass frequently at auctions and garage sales...mainly pink and green. I avoid it like the plague because any that I have bought cheap ($1) in the past, I was lucky to get my money back. I currently have a green glass (parfait I think) I use as a pen holder. Talking to dealers in my area, there is no market here for glass. If they drive down to Rockford, IL and put it in a shop, it sells like hotcakes. Go figure.
I use the rubber lid grippers you get free at events or businesses. Saves me from having to look for rubber bands which I can never find. Good tip though, hosman.
