Fold the front double with the good sides together and pin it down so the fold is neatly in the middle of the front dart.
Sew the front dart close, taking care to have the dart stop at the correct top end. The bottom is not that important as it will be covered by the pockets. But the top end of the dart will be clearly visible, so please make sure to have it end at the same height at both sides.
Once the front darts are closed, cut open the dart at the back. You won’t be able to cut it open all the way to the tip, but that’s fine. Press open the darts where they are cut open, and press the rest to the side. Take care to only press from the back. Pressing from the front will likely mark your fabric.
Apply a rectangular piece of light fusible interfacing around the chest pocket area so that it extends a few cm in all directions.
Sportcoats are typically made from somewhat heavier fabrics. That, and the fact that I prefer to use canvas rather than fusible interfacing, means that I don’t interface the front with fusible.
With the fusible in place, thread a needle and baste around the chest pocket to transfer the markings to the good side of the fabric.
This pocket differs from a traditional welt pocket. The welt extends above the pocket opening. This hides the pocket bag without the need for facings. The top part of the opening is also smaller than the welt, allowing you to slip-stitch it closed.
On the top line of your basted welt pocket, mark 0.5cm inwards from the corners of the top line.
These points are notches on the front part of your pattern.
Fold the welt double with the good sides together, and close the sides (sew the side seams).
Trim the seam allowances on the sides and especially limit the seam allowance towards the corner to avoid bulk.
Turn inside out so the good side is out and press.
Be careful not to overpress as you’ll be pressing from the good side of the fabric.
Baste a stitching guide at the bottom of the welt to mark the welt/seam allowance boundary. This will be the line to sew on later.
Place welt down on good side of front with the folded side downwards, and sew to bottom line. Make sure to stop and start exactly at the edge of the line you basted.
Place the pocket bag down on the front. The front with good side up, but the pocket bag with bad side up. Make sure to have the longest side of the chest pocket bag on the highest side of the chest pocket.
Only slanted chest pockets have a higher and lower side.
Sew this in place along the top line. Remember this should be shorter than the bottom row of stitches to attach the welt, since you marked 0.5cm inwards from the corners.
As the pocket back is typically some slippery fabric, you probably want to pin or baste this in place prior to sewing.
Now cut open your welt in the middle of both seamlines. Don’t cut to the edge, but create a trianngular shape there.
Flip the pocket bag and welt to the backside by passing both of them through the opening you just created.
Get everything to lay nice and flat, and press.
Now, bring the welt only to the front and get it to lie nice and flat. Press again from the back.
Resist the urge to press this from the front.
On the backside, fold the pocket bag double and sew it to the pocket welt below the existing seamline of the welt.
Thread a needle and hand-finish the chest pocket by sewing down the sides of the welt to the front panel (don’t let your stitches show on the front).
Finally, close the pocket bag by sewing the sides. Do this by placing the front down with the good side up. Then fold over each side and sew the pocket bag. While sewing these sides, make sure to catch those triangular little pieces of the opening. This will reinforce the pocket opening.
Baste the chest pocket closed while we contruct the jacket.
Cut out the front canvas piece in a light and supple canvas placed on the bias. Cut out the entire front.
Cut out the front dart and close it with a zig-zag stitch, making sure not to let the canvas overlap.
Cut out the chest canvas piece. Align it along the roll line, and baste it in place on front canvas piece.
The chest piece is marked on the front part of your pattern.
Now baste the front canvas and chest piece to your front. Keep in mind that the canvas has no seam allowance.
Base it a bit inwards from the seam line so you can fold it away when sewing these seams later.
You don’t want your canvas to get caught in the seams.
Time to feel like a real tailor, and pad-stitch those lapels.
Make sure to make the stitches a bit smaller towards the lapel tip, to make sure it lies flat against the chest, curling a bit inward instead of outward.
If you’re not sure how to pad-stitch the lapels, let us know and we’ll make an attempt to document it.
Now we are going to hand-sew tailor tape along the lapel edges of the front, and along the roll line. This will also secure the canvas to the front here and there.
Keep in mind that:
While sewing the tape to your front, avoid pushing your needle all the way through your fabric so that your stitches will show on the front.
At the same time, you should not secure the tape only to your canvas either. Instead, you should try to catch a few threads of your fabric on every stitch, so that the tape is secured in place, yet the stitches don’t show at the front.
This is less of an issue above the break point of your lapel where the fabric will be on the backside of the lapel.
Place your front with the good side up, and your side on it with the good side down.
Align the front/side seams, pin them in place if you feel like it, and sew them togther.
Place this down with the good side up, and place your back on top with the good side down.
Align the back/side seams, pin them in place if you feel like it, and sew them togther.
Make sure the canvas does not get caught in the seam.
If you have a double vent, this seam will contain the vent.
Sew the downward part of the side/back seam and the sideways part that forms the vent. Do not sew downwards after that.
Aling your two half-jackets with the good sides together, and close the back seam.
If you have a single vent, this seam will contain the vent.
Sew the downward part of the back seam and the sideways part that forms the vent. Do not sew downwards after that.
Align the shoulder seams with good sides together, and sew them together.
Make sure the canvas does not get caught in the seam.
Make sure to carefully align the shoulders based on the notches. Because of the different shape of the back and front panels on the neck side, the fabric edge looks different. So aligning those edges will not give you what you need.
So make sure to align the notches. It’s what they’re there for.
