I wanted a shelf to extend the entire length of our laundry room. It's 76 inches, so I had to modify the existing plan for one slightly longer shelf instead of three 72 inch ones.
Cut list for 76 inch floating shelf:
2 - 1/4 plywood strips @ 76" x 7 3/4" (top & bottom of shelf)
1 - 1 x 2 @ 76" (front of shelf)
2 - 1 x 2 @ 73" (shelf frame)
4 - 1 x 2 @ 7" (ends of shelf and shelf frame)
6 - 1 x 2 @ 5 1/2" (shelf frame studs)
I was able to build this using scrap 1x2 for the studs and ends. I bought two 8 ft 1x2 pieces and one piece of 1/4 plywood, which I still have a lot left of.
I have children and this was my first time building something on my own, so it took me any spare time I could manage over the course of a week.
I can't wait to build again! Thanks Ana!
