There are several different ways to cut crown moulding into a corner cabinet. Unfortunately, most carpenters today simply end their crown flush at the corner cabinet. Sometimes they are forced to do this because the kitchen designer forgets to add the neccesary fillers when the cabinets are ordered but most of the time it is due to lack of knowledge, skills or time. To add this type of return a 5/8" filler is required on the side of the cabinet as well as a 3" filler on the top corner. The 5/8" filler is then covered up with a piece of scribe moulding that has to be cut with a scroll saw at the top to contour the crown moulding.
