Before starting to build the framework, layout the plans and the die cut plywood sheets, and mark each part with its proper number using the parts locator drawings on the plans for reference.

Remove frames 1 through 13 from the die cut sheets. To remove frames, push on the front side of the wood die cut sheet. A light sanding on the back side also helps to release the parts.

Draw a longitudinal line down the center of your building board, then draw a series of lines perpendicular to the centerline every 2" along the centerline.
