For those of you who cut 2-ply on your CMC's, do you change anything with the slipsheet layers? Our Wizard usually has a 40 x 60 backing board, over which we lay a 32 x 40 slip mat for most projects. On top of that goes the mat we're cutting. Do you add an extra 4-ply mat, so it has two layers underneath, or just leave the one and set the blade deeper? Seems that a past thread had chats about layering 1 and/or 2 ply between larger sheets to cut it (not to be confused with the laminating that can be done with same). I also recall that perhaps Jim Miller has cut his mylar spider mounts by sandwiching mylar between two sheets of mat. I just cut a 2-ply mat to surround the art behind its mat proper, and it got me to wondering about all of this.
