Both Lowes and Home Depot sell partial sheets of plywood of various
thickness. Works well for mockup work.

Hi Lee et al,
I used to use cardboard for mockups but, for the past couple years I've
been using the corrugated plastic that's employed in temporary roadside
advertising.
It's stronger than cardboard, cuts easily on a paper cutter, and can even
be punched. Plus it holds together way better than cardboard with clear
packing tape.
I most recently used the technique for the redo seen at the bottom of this
page:

Some of the mounting plates required multiple mockups!
73 & Good morning,
