(5) Time to prepare the fronts: Take the canvas of the front and lapel, and trim back the seam allowances along the abutting edges, to sew together the pieces edge to edge, using a zig-zag stitch. Stop sewing exactly at the collar notch (x). Underlay the seam with a strip of bias tape (cotton). This method reinforces the joint and helps distribute stress across the garment.

Take the fronts from the fashion fabric and stretch the shoulder. Sew the lapel to the front, right sides together, and stop sewing exactly at the collar notch (x). Press open the seam allowances, and trim back the seam allowances at the collar notch.

Baste the front canvas to the wrong side of the front, lining up the edges. Start stitching centered down the front and continue along the front edge, following the roll line until reaching the shoulder. Give the front some ease while basting by stretching the chest slightly and simulating the body with a tailor’s ham or a pillow. Lastly, baste along the armhole and the side seam. Baste about 2” (5cm) from all edges.

(10) Sew the shoulder seam, right sides together, easing in the extra width of the back. Fold the front-facing and front canvas to the side while sewing. Press open the seam allowances and place the front canvas on top.

Let´s move over to some other tricky details with velvet and piping!

Mark the stitching line along the neckline, and baste together the layers (canvas and front) inside the seam allowance, right beside the stitching line. Trim back to 3/8” (1cm). Smooth out the front-facing over the shoulder seam towards the center back and mark the center back. Line up the front facings along that line, right sides together, and sew. Trim back the seam allowances and press open. That was the easy part.

The sleeve cuff shown here is different to the cuff described in the sewing instructions, but similar.
Sew together top and under sleeve along the front sleeve seam and attach the interlining with basting treads. In the sewing instruction, the interfacing reaches the bottom edge. Underneath you can see the cuff pined along the bottom edge, right sides together. I decided to use the fashion fabric for the cuff with raw edges to avoid bulk with that heavy fabric.

For that reason I used a cotton fabric for lining the cuff. The cuff lining is cut with seam allowances, these are turned in and pressed. The two layers are joined narrow by the edge with small stitches. Better than shown on the pics would have been to stitch down the vent facing (left side) and seam allowance (right side) first.IMG_4434IMG_4437
