Relax and enjoy your outdoor space with this DIY patio furniture set consisting of a sofa and chair. You can adjust the size to make them fit perfectly onto your patio or deck, and the sofa and chair feature arms that double as trays for al fresco dining. Make your cushions to fit, or buy store-bought ones and learn how to add ties to outdoor cushions! Deceptively simple to build, this DIY furniture project is made from pressure-treated wood, so remember to lay your timber flat while it dries thoroughly to avoid warping. This project can be completed over a weekend and will cost between $100 and $500.
