Lay the 2x2 stilt pieces on your work surface. Measure and make marks at 12 inches and 6 inches from one end of each stilt.
Mark three approximately equal distance crosses at 11”, 9” and 7” between the two previous marks (in the center of the 2x2).
Using the drill, drill three holes in the 2x2 in the crosses you just marked out for the foot holds to attach.
Place one foot hold block underneath one 2x2 and use the drill or a screwdriver to screw 3 of the screws through the 2x2 and into the side of the foot hold block.
