Build a shelf in a closet? I need to store hats and hat boxes
Install L brackets in the studs. Affix shelving board to the brackets.
Cynthia....I would purchase the vinyl covered wire shelving you can find at Lowe's or Home Depot, etc. To me would just be easier. Good luck
My suggestion is to first raise the hanging bar as far up as you can still reach comfortably to hang up a hanger. Then, under the clothes hanging up, in the lower part of the closet, mount your shelf. This way it will be much easier to access any boxes or other items that are stored on the shelf, rather than having the shelf way up high on top of the bar.
Cynthia, here is how one hometalk DIY person did it: https://www.hometalk.com/35211380/quick-closet-shelving
