We make moldings when catalogs do not satisfy. 
By moldings, we mean long, repeating pieces meant to run around rooms, not "anything molded."
Great pains are taken to create the pattern, either repairing an original or bench running a profile. Yes, we make those odd-looking sheetmetal and wood tools used for gliding through mounds of wet plaster. They also swing on a centerpoint to make radius arches, even complete circles. That's how we make the rims for ceiling domes. But these shown here were all cast in molds we made.
