There are a lot of ways to use iron plumber’s pipe to make shelves. Here’s the way that has worked well for me. Pipe shelving systems are not cheap but are a great investment because they can be disassembled and adapted to almost any setting. If you’re renting your current home or move often, they’re an excellent alternative to moving giant bookcases. If you own your home, it can be a nice, full-height bookcase for a study, shelving for dry goods in a kitchen or even organization in a closet.
