I'm float mounting a larger print (30" x 40") onto mat board. Typically for this kind of simple float, I'd cut a reverse bevel, hinge tape to the piece, and slide the tape hinges through the slot and secure them to the back of the board. In this case, the mat is too big for my mat cutter. My question is, will a cut just done with a straight edge work just as well to slide tape through and be secure? Or are there other methods to float mount I should be aware of and using. The print itself is rather heavy on BFK Rives I can't have it slipping. Thanks for your time and thoughts!
