Effective DIY hacks for small bedroom storage include creating a built-in bed nook with integrated shelves for books and essentials. Swap bedside tables for narrow floating shelves about seven inches deep, combined with plug-in wall sconces to clear surfaces. Use multi-functional furniture, such as beds with underframe drawers or ottomans with storage. Install pegboards or open shelves high on walls for decorative and functional display. Utilize vertical space creatively to maintain a tidy, spacious feel. These accessible hacks boost storage without sacrificing style or floor space.
