Place and align planks parallel on a level surface.
We recommend a soft surface to protect planks.
*Hint: Number the order of each plank for correct re-orientation, top to bottom.
Mark parts on back side or use masking tape.
Arrange the Rocks in an attractive and practical fashion. Position Rocks between
pre-drilled holes in planks. DO NOT position Rocks over any pre-drilled holes.
Mark hole position of each Rock in final decided position.
Flip each plank.
