Hello everyone, today I’m sharing details on my latest build: a 4′ tall 8-bit Goomba that doubles as a lumber storage cart. This is not the most practical of lumber carts, but it was a fun project that fits with my growing collection of retro video game garage decor.

Step 1: Cut parts according to the cut list

Break down the sheet of plywood into the following parts:
- 48″ x 48″ (Goomba)
- 42″ x 11 7/8″ (Dividers) x 4
- 24″ x 11 7/8 (Base)
Step 2: Draw grid lines for Goomba

Use a ruler to mark grid lines space 3″ apart.
Step 3: Route along the grid lines

Install a v-groove router bit and route along the grid lines. Use a clamp edge guide to ensure straight lines.
Step 4: Cut out Goomba’s silhouette

Trace out the silhouette of Goomba and then cut out the Goomba’s shape with a jigsaw.

Step 5: Paint Goomba’s pixels
Sand between the grooves and sand the surface of Goomba. I used a scrap piece of wood to support the sandpaper as I sanded between the grooves.

Tape off sections and spray paint the Goomba’s pixels.
