Q: I've collected some antique doorknobs, and I'd like to put them to use. Do you have any creative ideas? A: (Bruce Johnson, DIY antiques and woodworking expert) You could use a variety of vintage doorknobs to make a hat rack or coat rack. Better yet, make an apron rack for the kitchen (figure A). In that way, the doorknobs you're so proud of will be displayed even when aprons are hanging from it. It's an easy project. Here's how to do it.
