Underlining/Lining the Tremont Jacket


 In this hybrid underlining/lining method, the jacket is first constructed without completing the mitered corners, hems and neck facing. The underlining pieces are constructed separately in the same manner without edge finishing.

Once each jacket is sewn together, the two are then basted together as one jacket and the hems and neck facing are completed over the underlining. 
Use the jacket pattern in its original form to cut out the outer jacket.


When underlining the Tremont Jacket, the underlining fabric is cut out using the original pattern pieces for the outer jacket minus the bottom hem allowances and an adjustment at the center fronts.

Right Front and Left Front*

1. On Right Front and Left Front, mark a point ⅝" from the shoulder/neck dot towards center front of.
2. Draw a line parallel to the Center Front Foldline from this new point to bottom of Fronts. This is the underlining cutting line
3. Draw a line to extend the shoulder cutting line to the new cutting line from Step 2.

4. Measure 1⅝" from bottom edge to establish the hem foldline. Use this marked hem foldline at the underlining cutting line.


5. Repeat Step 4 for the underlining cutting line. 


Measure and mark a line 6½" up from bottom of Sleeve. This is the underlining cutting line.

If you are using a lining fabric that has a print or a definite right side, remember to flip the right and left front pattern pieces when cutting out.
