As you can see in the image, this shelf goes on both sides of the corner wall. It looks beautiful and can be used to organize books, trophies, pictures frames and many other things. The strength and design of the shelf depends on how properly you build it. First time workers definitely need some guidance to help them with the process. Therefore, I am including this basic video that I found on YouTube that demonstrates the process of making corner wall wooden shelves.
Some tools required to build a picture frame are a table saw, miter saw, measuring tape, wood glue etc. A table saw with a backing board and miter gauge can be used to get the right angle and lengths of picture frame every time. You can use builders square to arrange the final cut pieces before nailing, screwing or gluing. Check out the video tutorial below for more details.
