Nice use of materials you already had! Digging the color choice as well.

where are the directions to make and hang?

Take three 12x12 boards and cross rip to create your tops and bottoms of shelves. Then get a 1x1” piece of trim and cut six small 5” long strips and mout to 3 of the triangles along the corner edge. (These art how you will mount in wall. Then clamp the three sections together and measure for the front trim. I had about a 3” piece needed and rip sawed a piece of pallet wood then cut face sections to fit. To mount on Wall you will need self tapping screws a screwdriver, level, and measuring tape. I spaced my shelves about a foot apart. Take the piece with your 1x1 mounting strips and secure to wall once level with 4 screws two in each side. The. Add the top and put one screw in the back corner mounting it to base. Add faceplate and secure with a couple of screws or if you prefer finishing nails. Repeat for each shelf and you will have it. I suggest leveling during each step to ensure you have the look you are going for. Good luck!!!

We love the clean look of a floating shelf!

What a great find and facelift!
