STEP EIGHT:
Create two gusset-style sides for the top. Start with two 4-1/2" x 4” pieces. You’ll need to create a 1-1/2" bend on your 4” side; but first, cut 1/2" x 1-1/2" off the top of the side. Then on the other topside corner, measure down 1” from the top and cut the bottom corner off between the 1" mark and the 1-1/2" mark for the bend. You’ll do the same on the other piece, just mirrored.
