Marching Fort corner (part 1)

I was unsatisfied with cutting the the pink foam with the coping saw, so I went by the hardware store near work during lunch and scored one of these beauties. Night and day, hands-down a better tool for the job.

Last night I did some sketching and tonight I cut the foam for a corner section. I was amazed at how much more precise the cuts were. I was ready to build Troy out of pink foam!  =]

The cut below was a little rough. Not sure if my technique was off or if there is actually a grain to this stuff?

I guess a square corner section might make more sense, but the only big plywood bases I had were rectangular. Meh...
