I can’t be the only person irritated by the fairly untidy nature of inseam pocket finishes. Often we are lining garments, and in that case there is no need for pocket finishes to be perfect. But for other articles of clothing – like hoodies or simple pants – these pocket finishes will be visible when the garment is inside-out.
I fiddled around and finally came up with a very quick, reliable, and easy method for a good pocket finish. This method uses a sewing machine for the stitching line and a serger for the finish, but you can also zig-zag and trim in place of serging.
So first: cut your pieces as per usual, except use thread-tails, chalk or washable marker to mark your pocket position in the side seam, rather than clipping into the seam allowance.
Now, we have the four pocket pieces – I call them “kidney-shaped” although that’s not perfectly accurate:
We are going to serge-finish the curved edge first. Go around the very edge, careful not to trim any of the piece:
Now, we are going to serge the straight edge, leaving long tails:
Next, take these long tails and, using a blunt darning needle, thread them through one of the curved seams and trim. You will end up with a perfectly-finished pocket seam:
Now, finish the side seams only of both the front and back piece. Below you can see my black thread tail marking the pocket position:
Pin your pocket to your side seam, right sides together:
Stitch 1/8″ from the seam allowance, starting right at that pocket piece and performing a firm backstitch at the beginning and end of the stitching line. This garment is made with a 3/8″ seam allowance, so I stitched at 1/4″ from the finished edge:
Now, either steam-or finger-press this last seam, then press it open such that the seam allowance faces to the pocket. Press again, if you like. Stitch 1/8″ from the seam along the full length of the pocket, catching all layers:
Here is the underside of that understitching – it looks great!
And here is the view from the public side of the garment:
Once you’ve completed the pocket join for all four pocket pieces, it’s time to join the shoulders and then the sleeves. Finish the sleeve long edges before joining to the body, join the sleeves as the armscye, and finish the armscye seam leaving long serge tails.
Next, pin the side seams of the garment together:
You want to really get your pocket pieces lined up exactly. Sometimes that understitched seam allowance will want to push towards the body of the shirt while you are sewing the side seam and pocket closed. To keep this from happening, I usually sew this long side seam from the sleeve hem, and then stop in the middle of the pocket curve. Then I flip the garment over, and sew up from the shirt hem, meeting in the pocket curve. This keeps the seam allowances from trying to push away from the pocket.
When you get to pinning your pocket curve, really make sure the pockets are lined up perfectly with one another. If you cut accurately and you did not trim anything with the serger blade, they will line up beautifully:
Now, it’s time to sew that side seam. Take your time and really make sure your finished edges line up well together.
When sewing toward that pocket I usually “cut over” from the side seam allowance, to stitch right on the finished edge of the pocket kidney pieces. You can of course maintain the garment seam allowance instead, and then go back over the serged edges with a stitching line on a second pass, if you like.
Here is that underside of the pocket – it’s perfect!
Finally, those long tails we have at the armpit? Knot these and then slip them into an inner serging channel. A firm finish, and a good-looking one too!
Those are some sexy pockets!
So to sum up, the method is fairly simple:
1. use thread marks, not clips, to mark pocket location
2. clean finish the entire kidney-shaped pocket piece
3. finish the side seams, leaving long serge-tails at the armpit and hem
4. sew the pockets to the side seams, right sides together
5. understitch the pocket side seam to the pocket
6. join the shoulders, sleeves, and then side seams of the garments, keeping a very exact seam allowance
7. continue to finish the shirt
