Project: magnetic boards

So there are some really cool magnetic things out there, but my mum won't let us put stuff up on the fridge and I don't have any magnetic surfaces other than my chalkboard in my room. I didn't want to use my chalkboard for too many magnets or things like that...it's not that big! So I looked around...and decided on a new project. 

I bought two baking trays from Kmart, $5 and $8 each. 

Luckily one came with a hole in one side like this. 

So I threaded a ribbon through it and hung it up with a command hook. 

 ( the picture is my notes for a tinkerbell costume so I wouldn't forget my idea)

I was going to cover them in fabric to pretty them up, but I didn't have any pretty fabric and didn't see anything good whilst I was out shopping so I decided it didn't really matter.

The other tray is a dilemma. I'm having lots of ideas and I'm not sure what to pick. 

Option 1: attach mounting hooks or tape to raised edges and stick it up with the raised base sticking up. ( think sticking a baking pan upside down)

Option 2: attach mount to bottom of raised base and stick up with the edges raised and the base indented. (Think sticking the pan to a wall with the side you would cook on visible)

Option 3: pick either way of mounting but paint around the edges to add colour.

So what's your verdict? Any suggestions?

I shall post an update once the second tray/board is up.
