I have a very narrow closet with sloped ceiling. (Only one end has a door.) Any advice for improving the usefulness of the space would be appreciated, but I'd mainly like to learn some specifics about the Ekby Riset brackets designed for these kinds of spaces. What kind of hardware would I need to attach them to the wall and to attach shelves to the brackets? How wide are the brackets/what width of shelves would I use? Is there a limit to the length of shelf recommended? Thank you!
