Now here's how to achieve this look. First you need to cut 1 hair canvas from your collar piece and mark it like so:

In my example, the roll line is marked in red (with red arrows pointing to it). The seam allowance is marked in pink chalk all the way around the collar. Finally, I've marked lines for pad stitching in blue pencil. The area below the roll line (the stand) gets 1/4" pad stitching. (This means that the stitches are 1/4" long and 1/4" wide.) The area above the roll line (the fall) gets 1/2" pad stitching.
Place the hair canvas on top of your under collar fabric.

Baste along the roll line with uneven basting stitches.

Now you can pad stitch the stand (the area below the roll line). Make 1/4" pad stitches and roll the fabric (with your index finger under the roll line) as you go. Do not stitch into the seam allowances.

After you've finished the stand, turn the collar around and pad stitch the fall (the area above the roll line). These stitches are bigger, 1/2". Continue to shape the collar with your hands as you stitch.

Your finished pad stitching will look like this.

Trim off your seam allowances.


Next you're going to steam your under collar and leave it to dry overnight. Pin it around a tailor's ham as it will be rolled around your neck.

I propped mine up against a seam roll. Now, spray it with water and steam the heck out of it. Do not press down on your roll line. You're just applying steam, not pressure.

Leave it to dry overnight. Next step: sewing and shaping the upper collar! You can start now by applying fusible interfacing to your upper collar piece.
