Molding Returns

The Problem

Where a baseboard run ends at a door casing, the casing is often thinner than the baseboard. Cut the baseboard square and the end grain faces into the room with the moulded profile — the ogee, bevel, or bullnose along its top edge — sliced through and exposed. Painted, that end grain absorbs more than the faces do and dries to a different sheen, so the cut stays visible after two coats.

The same thing happens where baseboard dies into a cased opening, a hearth, or a stair skirt.

The Technique

A return closes the profile by carrying it around the end of the board and back to the wall.

1. Cut the end of the baseboard at 45 degrees, with the miter opening toward the wall — the same cut you'd make for an outside corner.
2. Cut a matching 45 on a piece of offcut from the same stock, then cut it off square a few millimetres behind the point. You want a small triangular wedge whose mitered face mirrors the one on the board, and whose profile matches because it came from the same length.
3. Dry-fit the wedge against the board. The two mitered faces should close with no gap and the profile should run continuously around the corner.
4. Glue the wedge on. Don't nail it — it's too small and it will split.
5. Hold it with a piece of painter's tape stretched across the joint until the glue sets.

The board now ends in its own profile, with no end grain showing.

The Problem

Where a run of shoe molding dies out — at a door casing, a cabinet end, the last stub of a wall — most installers finish it with a quick back cut: an angled slice that tapers the end down to the floor. It reads as done-in-a-hurry, and it leaves end grain facing the room. Trim carpenters have a cleaner standard detail for this: the finish return, where the molding's own profile wraps around the end and dies square into the wall.

The Technique

The trick is to cut both halves of the return before you ever handle a small piece.

1. Measure to the point where the shoe terminates and cut the run with an outside 45° miter there.
2. Take the offcut (or a scrap of the same stock), flip it around, and cut the opposing 45° on its end.
3. Now cut that mitered end off flush — square across, right behind the miter. You're left with a small triangular return piece.
4. Glue the return onto the mitered end of the run with CA glue and spray activator. It sets in seconds, and there's no room for a pin nail in a piece this small anyway.

The profile now turns the corner and lands flat against the wall — the same detail you'd expect on the end of a stair skirt or a window stool.
