Another session of carving yesterday's foam and adding today's foam.
I used 4 cans total for this build. I used the original red great stuff foam the first two applications and used the blue door and window for the last two. I used the red cans first because they were what I had on hand, and I'm glad I did. The foam is more rigid and holds the wood. The blue can expands less and is more spongy when cured. That is annoying when I am trying to carve it because it keeps squishing rather than tearing. I doubt that it would be rigid enough to hold the weight of the wood in place.
