layered molding. Layered molding is basically a glued-up stack of full-width boards with the profile routed across the front and ends of each board,see Fig. 2.
Layered molding is faster to make and easier to install than strip molding because you don't have to deal with mitered corners. All you have to do is cut each layer to finished size and then rout the profile.
Note: When gluing up layered molding, the pieces can become quite slippeiy and slide around. To keep the strips aligned during glue up, refer to the margin tip below right.
The only disadvantage I've found to layered molding is the exposed end grain. But by sanding the ends several grits finer than the rest of the project, it's less noticeable.
Design Note: As a general rule of thumb, I limit the width of layered moldings to workpieces around 5" or less. Anything wider has a tendency to warp with the changes in humidity.
One of the things I like best about built-up moldings is you don't need a whole cabinet full of router bits. For the six profiles shown below, I only had to use four common router bits: a cove bit, a Roman ogee bit, and two round-over bits, see box in upper right-hand corner.
Round-Over. Round-overs come in many sizes. They look best on the top of a molding.
Cove. Coves also come in a variety of sizes. It's the profile I use most often on the bottom.
Roman Ogee. A Roman ogee looks good in the middle or at the bottom of a molding.
Straight Cut. One of the simplest ways to top off a profile is to add a straight-ripped edge.
As you're making profiles, try experimenting by rearranging them in a different order to change the overall appearance of the molding. Or change the thickness of the pieces that make up the molding. You can vary the number of strips or layers, or even the bits you use to rout the profiles. The possibilities are endless.

To keep layers aligned during glue up, nail a few wire brads in one of the layers. Then snip off the heads of the brads.
