We have a copy center at work. I called down and asked how much it would cost to cut 75 sheets of paper (for 150 copies of the invitation), and sent a PDF of the document so she could see how many cuts it would take. She got back to me and said $4. I said, DEAL.
So I dropped them off at the copy center downstairs from my office, and picked them up the next morning. And they turned out fantastically. I was a little bit worried handing it off (worried about straight lines, words getting cut off, etc.) but it turned out the slight anxiety was for nothing.
By my calculations, that $4 saved me from making a total of 450 cuts.
Next up: the pocketfold inserts!
