Jacob's grandma got him some metal stars for his birthday. We decided to make some art with them to hang on his wall.
The plywood is 21"x21". I measured out and marked the lines for the 7" square boxes. Taped it all off and then primed and painted the squares I wanted white. Then I glued the stars on and nailed the trim pieces on. All that was left to do was add some picture hanging wire to the back and hang it on the wall in Jacob's room.
