That made me laugh. I remember all too well walking around in an office supply store when I lived in the UK. I was looking for thumb tacks and couldn't find them. Even when an employee came to help she couldn't as she didn't know what a thumb tack was. Turns out they are "push pins".

So, now I have a mental image of my door panels being held on with thumb tacks. Kinda ghetto looking, but might add some bling if you use the chrome ones.
