I’m not giving dimensions for this project because I honestly didn’t measure once! {My favorite kinds of projects.}
I cut the long 1×8 piece first. It’s approximatly 21″ give or take. I then eyeballed the shelf size. I didn’t want it sticking out too much. I also needed to considered the size of the trim. I made two cuts, once for the shelf size and once to accommodate for the trim. I stacked the trim and drew a quick mark. {Yay! No math!}
After those the shelf was cut, I just needed to cut the trim out of 1×2. Three quick cuts and I was done! Make sure the front piece is the longest! This gives a more finished look.
Once all the pieces were cut, a quick sand with my orbital sander and I was ready to assemble!
