Step 1: Supplies
Straight edge to cut with
Standard Foam core boards (I used 6)
2 - 8 Foot pieces of Trim
Step 2: Measure and Mark
On the opposite side, just measure and mark half way at the 15" mark.
Step 3: Cutting the small teeth
Then from that mark, cut across to the 15" mark.
From that one, cut across again to the other 7.5" mark.
Your pretty much zig-zaging across the board to create 3 teeth.
Save the 2 outside "half teeth" for another project.
Step 4: Cutting the BIG teeth
Again, try to save the "half-teeth" extras for something else.
Step 5: Test layout
If you use these exact measurements, you should be about to put 5 small teeth and 1 long tooth on an 8' board.
Remember, your going to be making 2 of these sets, so set your "big" tooth where you want to create that vampire look.
Step 6: Glue and clamp
Then clamp each tooth and let it set overnight to dry real good, You don't want a toothless house!
Step 7: Duct tape and drill
Then drill about 3 holes in the boards down the whole side of it to secure to your home.
