I am making my own pocketfolds for the invites....I was bummed pricing out how much it would be to have the textured posterboard cut (.50 to .75 per cut, times two cuts per board, times 30 boards!)
BUT....I went to FedEx Office yesterday and they have a giant paper cutter that you can use for FREE! Woo hoo! It took me about 40 minutes to cut everything

HTH!
