So I finally bit the bullet and invested in some giant sheets of 640 gsm hot pressed Fabriano paper. Now, I'm wondering how to cut them. They're thick as cardstock, and my usual box cutters aren't working very well for a clean cut all the way through. How to cut these sheets of paper? I am thinking of taking them to a framing shop and seeing if they can cut them into A4 size papers or the like.
