You've made so many! Are you selling them?
I recognized the vases as typical style for gift fresh flowers. I've seen a bunch of them even offered free on Craigslist. And someone probably not more than 15 min drive away is offering a large -- 12"? -- round/nearly spherical glass bowl for a bit of $. I think It was for $10-15 in fall which I successfully resisted, but apparently no takers then, because it's up again for $6 or something this time.
I have to chant to myself -- "I don't have room for terrariums ..."-- about 50 times every time I see that, and you are NOT helping by posting these fun creations.
