You may already know this, but. . .
. . .just in case you don't:
If you have a very large glass vessel (or, let's say, a cloche) that you want to fill with items that are fairly expensive, or you just run short of enough of the things to fill up the cloche (for example: this 20-inch cloche and the faux candy hearts), insert a glass cylinder, like a jelly jar, clear glass vase or chimney, and slip the items be between the cloche and the chimney.
Hope this makes sense.
And now that I've seen what this looks like in a photograph, I running to get some pink ribbon to tie around the top knob!
