Whimsical Foam Birdhouses

The hole is most easily cut with the Hot Knife
. The boxes can be fixed to a wall with a single screw, but a large washer or similar item (I used picture hanging plates), should be used to ‘spread the load’ and negate any chance of the screw being ripping through the polystyrol. The washer/plate then ‘clamps’ the box to the wall.
