DIY wings made out of paper plates. Make a template to glue plates to- add gold glitter spray to edges of plates before cutting- add a gold wire ornament wreath to center, and flip the wings so they aren't upside down- would be pretty fantastic!
This is a cloche. Cloche means bell in French. I believe a cloche was originally referred to as a small glass dome used to force plants to bloom (like a mini green house). But in decor terms, it's usually a display (raised on a stand) under glass.
