It is the "for sale" signs - not the solid thinner, flexible, plastic but literally looks like white plastic cardboard. I used the rotary cutter (I know, it was an old blade though:) ) and used extra pressure to cut it. I covered it with fabric and if it is soiled, it can easily be cleaned. It only cost $6 for what I needed. And did I mention it is very lightweight!
I can make a fairly substancial bottom by ironing craft backing to a couple layers of fabric. I try to cut it so that there's an "unbacked" border around the bottom pieces. The craft backing is pretty stiff, so a few thicknesses get to be hard to sew thru
