Anyway, got commissioned to do an M77 Paladin out of foam. Relatively simple, though due to all the open areas in the middle of the gun, I opted to try out a different method.
Once all those layers were glued down, I cut out the puzzle pieces, glued them all together, then used the extra to cut out the small bit at the bottom of the grip.
After assembly, I grabbed my craft foam and cut out the top layer.
Oh, and, naturally, the paint and weathering. ;)
