In the following tutorial, I will explain step by step how to sew a front trouser pocket in various shapes using video and illustrated text instructions. These pockets are also known as wing pockets. They can be shaped in different ways. Straight pockets are also referred to as “French pockets”. I chose the square shape for the instructions because it requires an additional processing step compared to the straight shape. I will explain what else you need to consider with the round bag shape (referred to as “banana” in the configurator) in the relevant sections.

Video instruction:

The instructions for the square bag shape are not included in the video. If you have decided on this shape, please take a look at the following illustrated text instructions so that you know what you need to pay attention to.

1. This is required:

Pattern pieces made from shell fabric:

Front pieces (VH) – 1 pair (the pocket opening is already cut away here – see last point of the fitting instructions)
Upper pocket bag facing (TBOB VH) – 1 pair
Lower pocket bag facing (TBUB VH) – 1 pair

Pattern pieces made from lining fabric:

Upper pocket bag (TBO VH) – 1 pair
Lower pocket bag (TBU VH) – 1 pair

Tools and aids:

Pins or clips
Hand shears
Edge tape (for straight pocket opening: e.g. T20 from Vlieseline; for shaped and angular pocket opening: e.g. T12 shaped tape from Vlieseline)

2. Sew pocket facings onto pocket bags

The picture shows how the pocket bag covers are finished. — Neaten the front edges of the facing.

The front edges of the upper and lower pocket bag facing are finished with an overlock or zigzag seam.

The picture shows how the pocket covers are attached to the pocket bags. — The pocket covers are attached to the pocket bags.

Then place the top facing on the top pocket bag and the bottom slips on the bottom pocket bag so that the shape and notches on the back edge match.

In this example, the direction of the pocket lining is chosen so that the right side of the pocket lining is visible when you look into the trousers. Consequently, when you look into the pocket opening, you can see the left side of the pocket lining. You can also switch sides so that the “nice, right” side is visible when you look into the bag.

The picture shows how the pocket facings are quilted onto the pocket bags. — The pocket facings are quilted onto the pocket bags.

The facing is stitched onto the pocket lining with the right side facing up 3 mm from the edge inside the overlock seam. With thin fabrics, it is also possible to fold over the edge of the facing 1 cm wide and topstitch it; it is then not necessary to finish the cut edge first.

3. Secure the pocket entry on the front piece

The picture shows how the front pocket opening of the trouser pockets is reinforced so that it does not wear out. — The pocket opening is reinforced with matching tape to prevent it from stretching.

The edge tape is ironed onto the opening edge of the pocket. This is to prevent the procedure from expanding. If you don’t have any ribbon available, you can also cut a strip of fusible interlining.

In the picture you can see how the tape is worked in two pieces on the square pocket shape and ironed on at the opening. Next to it you can see the straight tape that is suitable for the French pocket, and next to it you can see how you can lay the shaped tape so that it fits on the notch with the rounded “banana”. Form fits.

4. Sew on the upper pocket bag

The picture shows how the front pocket bag is sewn onto the front trousers. — The pocket pouch is placed on the opening edge.

The upper pocket bag is now placed with the facing side on the right side of the fabric of the front trousers at the opening with the edges matching, pinned in place and sewn together with a straight stitch at a seam width of 1 cm.

5. Seam allowance for a square or round pocket entry

The picture shows how the seam allowance must be cut into the square pocket. — The seam allowance is cut in.

With the square pocket shape, the seam allowance is cut exactly in the corner to just before the seam. Be careful not to cut into the seam.

The picture shows how the seam allowance is cut into a round notch edge. — The seam allowance is cut several times in the curve.

In the case of a rounded or shaped pocket opening, it is important to cut the seam allowance 3 to 5 times up to approx. 2 mm in front of the seam. It is also advantageous to offset the incisions in the layers so that they are less visible on the outside. As the square pocket opening is slightly rounded at the top, the seam allowance is also cut into this shape. This step is not necessary with the straight pocket opening.

6. Turning and topstitching of the raw edge

The picture shows how the opening edge of the front trouser pocket is ironed after the front pocket bag has been sewn on. — The seam should be ironed before the pocket bag is turned inside out.

Before you turn the entry, you should iron it over.

Depending on the design, the pocket opening can be designed with or without visible quilting. If you opt for the “without quilting” version, a bottom seam on the facing side ensures greater durability. When the trousers are positioned as shown in the picture, the facing is topstitched to the seam allowance approx. 2 mm from the seam.

The picture shows how the opening edge of the trouser pocket is stitched at the front with a decorative seam. — The opening edge can be stitched from the outside with a decorative seam.

If you want a visible seam on the front of your trouser pocket, topstitch the pocket opening at a distance of 2 to 6 mm from the edge on the right-hand side.

7. Place front piece on lower pocket bag and secure

The picture shows how the trousers are placed on the lower pocket bag. — The front trousers are placed on the lower pocket bag.

The front trousers are now placed with the opening edge on the lower pocket bag at the notches or markings on the facing. The right side of the fabric of the front trousers and the facing of the lower pocket bag are visible from the top.

The picture shows where the lower pocket pouch of the trouser pocket is secured at the front with a few stitches so that nothing slips. — The lower pocket bag is secured with a few stitches.

Now fasten the raw edge with pins or clips so that the facing and front trousers form a harmonious line at the waist edge and side seam. Secure at the two marked points with a few stitches so that nothing can slip out of place.

8. Sew the pocket bags together

The picture shows how the upper and lower pockets of the trouser pocket are placed on top of each other at the front. — The upper and lower pocket bags are connected.

Now the pocket bag still needs to be closed. To do this, the top and bottom pocket bags are pinned together.

The edges of the pocket bags no longer fit together exactly after all the workingsteps. It is important that the edges are not pulled together exactly, but are pinned together smoothly. If necessary, you can trim the edges before sewing them together.

The picture shows how the edges of the pocket bag are finished. — The pocket bag is finished.

The seam is closed with a straight stitch and the raw edges are finished with an overlock seam or a zigzag stitch.

You can also close the edge with a right-to-left seam. If you would like to know how to do this, take a look at the instructions for the front slit pocket on a pair of jeans.

9. Pleat option

The picture shows how the pleat is folded at the waist. — The pleat at the waistband is folded according to the markings in the pattern.

If your trouser shape has a pleat at the waist, this should now be folded and secured in the next step.

10. Auxiliary seam on the pocket bag

The picture shows how the pocket bag of the trouser pocket is secured at the front within the seam allowance. — The pocket bag is secured inside the seam allowance.

Now everything is being ironed out again. The pocket bag can be pinned at the top edge and side seam and joined to the front trousers with an auxiliary seam at 5mm edge distance, which makes further processing easier.

11. Top stitching with angular edge

The picture shows how the lower part of the opening edge of a square front trouser pocket can be finished with a decorative seam. — An additional decorative seam can be added to the angular folded edge.

Depending on how you like it, you can topstitch the lower, short section of the square trouser pocket at the front with a decorative seam. It is best to try it out first to see if the pocket opening is still large enough.

12. Finished front parts

The picture shows what the finished trouser pockets look like at the front. — The finished side pockets.

This is what the finished front trouser pockets look like – here in the square shape.
