Corrugated.

Wrapping up some bits and pieces today and came across some corrugated card. I'm really bad/good (delete as appropriate) when it comes to collecting stuff like this. It's probably a hangover from my childhood. If it could be reused, it was kept. The Christmas wrapping paper was a good example. Like all the other decorative stuff the good bits were folded neatly and tucked away in the loft for the next year. Changed days I guess, but I still keep the odds and ends that are harder to come by.
