Having a nice baseboard is really important. The baseboard must be sturdy, the edges must be neat and the bottom should have some feet attached. Before purchasing any board, review your contest rules. Most contest rules will state something about the minimum thickness as well as the maximum dimensions of the baseboard.
No matter what the dimensions, I recommend using either a maple or oak baseboard, 1/2″-3/4″ thick–make sure it is flat (no warping). I definitely use a 3/4″ for my heavier gingerbread projects. You don’t want to make a beautiful gingerbread masterpiece just to see it crack because the baseboard has warped!
Edging ideas
Once you’ve cut out your baseboard to the proper dimensions, you’ll need to clean up the edges. You can sand the edges, fill in any holes with wood putty, sand again then paint the edges and the top of the board. Or, you can glue a nice ribbon around the edge. I prefer to use a wood veneer tape around the edges, it gives more of a natural look. It can also be stained, if you want to get fancy! The veneer is ironed on (sometimes I have to glue with wood glue), then trimmed with a special trimmer. No matter what you do, ensure that your edge is neat and it fits with your project theme.
Let’s talk about feet!
Feet are important, especially when you have a heavy project. They help you get your fingers under the board to lift the project and protect your work surface from scratches. I’ve used thick Scotch brand felt pads mostly. If you want to get a little fancier, you can use furniture legs. Some caveats when using furniture legs: get the kind that do not require screws (can go through your baseboard) and use felt pads under them so that your work surface isn’t scratched. The furniture bun legs I’ve posted on the right come with screws, but I would use Liquid Nails to adhere them instead of screws. (Note: Liquid Nails require a caulking gun). Another idea, I haven’t personally used, but I’ve seen it with other projects, is attaching a lazy Susan (we call it a carrousel in our house!) to the bottom of your board. It is especially nice when you want the judges to be able to turn your piece.
Something else to consider when choosing your baseboard feet is the extra height it will give to your project. Many contests have a height limit. Be aware that they measure from the table to the highest point on your project. Some contests merely deduct points, others will completely disqualify you.
