Cool little floating corner shelf. This one is for a 50” flat screen which was given to us and is too big for our armoire. To find out how far out you need to come from the corner, use the Pythagorean theorem (a^2 + b^2 = c^2) where c is the max width of your shelf. I just used 1x1 lumber from the hardware store with plywood on top cause it’ll be up out of the way. I countersunk screws and sanded the front and rounded the corners to make it look cleaner.
