:o Get down to your local Ryman's Stationary Shop. They're currently selling their large corkboards (the ones that are 60cm x 80cm) for just £4.24! I picked one up today because I've completely run out of room on my current corkboard, and my pin book is full too! It's not the strongest-looking corkboard I've ever seen, but for £4.24 I think it's a bargain!
