Treasures under glass

I have a house full of cupboards - full of tins - full of treasures - and I bet you do too! I love knowing that I have them but I definitely forget what I have. Does that happen to you? So I love this idea of having 2 or 3 glass cloches that you display tiny vignettes of our prized miniatures in - to admire - and then swap them out for another selection when we get tired of them. This is a fun tutorial, at 2 Gypsy Girls, on how to make said displays - now where can I find those cloche(for a reasonable price?)
