Some advice please?

Hello, I'm new here and this is my first post.

I need some advice. I've been practising my glass engraving on bottles, but I don't know what to do with them now.

The bottle is a normal alcopop type bottle, with a Slytherin crest (from Harry Potter) engraved on it (I know it's a bit hard to see!).

This is a picture of the crest that is on the bottle.

The engraving stands out  better with a dark background, but I have no idea what to do with the bottle to best display it.
