I'm tackling my first DIY project by building a wooden shelf for my garage. It won't be attached to any studs or walls and must be free-standing. Initially, I designed it without diagonal bracing, but I'm starting to worry that might be a mistake. My thought was to use 45-degree braces since they're easier for me to cut with my current tools. However, this means there would be about a 1-foot gap between the braces and the corners. Since the shelf isn't meant to hold heavy items, I'm wondering if it's necessary for the braces to reach from corner to corner, or can I leave that gap without compromising the shelf's stability?

Going corner to corner with the braces is usually the best option because it provides the most stability and prevents racking. However, it does use more materials and can limit the open space. An alternative is using large triangular gussets in the corners or going horizontally across two corners if your shelf isn’t too deep, which might save materials and still offer decent support.
What you're building is kind of like a narrow console table. You might find inspiration by looking up designs for console tables—they often have good stabilization methods you can adapt for your shelf. Just remember to secure everything well to keep it from wobbling!
