Step 2: Make The House

If we had used thicker wood, it is hard to beat biscuit joining the corners, but with the thin plywood I had around, there would not have been enough material to hold the biscuits.

Thus, the assembly process was to spread glue on the edges, clamp it together, and then glue and screw the cross pieces.
