Ironically, the thing that takes the longest to do is cut the big pieces of mat to the 8x10 size. Not that the actual cutting is what takes the time, it's the time it takes me to summon up the energy to clear the floor, and wrestle with cutting the mats by hand. I have a small guillotine, but it won't help with the big pieces. I have 6 papercuts ready to be mounted, but I haven't sat and gotten them cut. Maybe it's worth an extra trip to somewhere that will cut them for me.
