When picking out vintage post, make sure there is a flat section in the post so you can attach the corbel against it. Also, when picking out the corbel, be sure it has a straight 90-degree angle. Some corbels are tilted for porch roofs.
Cut one of the pieces of plywood into two pieces, one at 12" x 11" and the other at 3" x 12". The bigger piece is for the name of the inn, and the small piece is for the "vacancy" part of the sign. Sand the edges of each piece smooth. Create curved corners on the top of the 12" x 15" piece of plywood. We used a dinner plate and a ruler to trace two equal curves; you could also use a compass or a protractor.
Pre-drill holes at the top of the "vacancy" sign and the bottom of the main sign. Match up the holes so you can attach each piece of the sign. Insert teacup hooks in each of the pre-drilled holes, and hang chain from the hooks. Do the same for the top of the main sign onto the bottom of the bracket on the post.
