To corral shelf-dwelling books or DVDs that like to wander, cut 3/4-in.-thick hardwood pieces into 6-in. x 6-in. squares. Use a band saw or jigsaw to cut a slot along one edge (with the grain) that’s a smidgen wider than the shelf thickness. Stop the notch 3/4 in. from the other edge. Finish the bookend and slide it on the shelf. Want to build the shelves, too? We’ve got complete plans for great-looking shelves here.
Google is probably the first place where most people would start searching for woodworking plans, but often the top results can be a mix of articles and how-to pieces that just aren’t detailed enough. Sometimes they’ll link to the plans (like we try to here at Lifehacker), but other times, they’re just showing off a cool project. There are better, more precise ways of finding what you’re looking for.
