I'm not a fan of chipboard. I don't use it but if you do, ask yourself these questions:
Is it outdated?
Is it in good shape?
Is it easily stored (tiny pieces usually are a pain and not worth it)?
Is it something I TRULY will use?
Do I look at it with excitement or is it just okay?
Do I have specific pages I want to use this with?
Could I get along without it?
Is it more than a year old?
If the answers aren't good, neither is keeping it.
