The children’s treggings »LaLeggie« (110–152) have the look of real trousers, unlike normal leggings. The word is ultimately composed of “trousers” and “leggings”. For cool kids who like to wear tight-fitting trousers but still want comfortable trousers, »LaLeggie« is perfect. A hinted fly, fake pockets at the front, a yoke at the back and classic patch pockets look like a pair of skinny pants. Elastic knitwear such as Romanit or pique allow a tight leg like you know from leggings.

Have fun sewing!

Sew the fake bag and fly

Fold the fake pocket edge of the front leg inward around the seam allowance and iron it smooth. Place the fake bag under the front leg and sew it close to the fold edge of the leg with the twin needle. Work the second fake bag the same way.

Use the twin needle to stitch a fake fly on one of the two front legs.

Sew back pockets and sew on yoke

Iron the seam allowances inwards and also fold the hem allowance of the top edge inwards and iron them smooth. Cut off the excess seam allowance on both sides. Topstitch the hem edge. If you like, you can now iron on a cool patch and sew it on.

Pin the back pocket left to right on the back trouser leg and sew it on. Secure the beginning and end of the seam well or secure the ends with a small triangle. Work the second bag in the same way.

Put the yoke on the right leg on the right leg. Make sure that the higher part of the yoke points to the rear center. Sew the two parts together with an elastic stitch and iron the seam allowance down. Stitch them with the twin needle if necessary. Work the second, rear leg in the same way.

Close side seams and connect pants legs together

Place the front and back leg section right to right on each other and pin them together on the sideline. Sew the two cut pieces together with an elastic stitch. Iron the seam allowance back and stitch it with the twin needle. Work the second leg in the same way.

Place both trousers parts on top of each other on the right and put the front center and the back center together. At the center back, make sure that the two seams on the yoke are aligned. Sew the two together with a durable, elastic stitch.

Place the front crotch seam right on the right on the back crotch seam so that your treggings look like trousers turned inside out. Pin the two inside leg seams. Sew them together in one go with an elastic stitch.

Sew elastic band

Fold the elastic band together on the short side right to right and close it to form a ring. Iron the seam allowances apart.

Fold the ring in half in height left to left and mark the center front on the opposite side of the seam. Iron the folded edge and topstitch it with an elastic stitch. Make sure that the waistband remains wide enough for your rubber band even after sewing on.

Slide the elastic band into the pants turned on the left. The seam of the elastic band meets one of the two side seams. Pin the elastic band unstretched and sew it on with an elastic stitch. Leave a feed opening of approx. 4 cm.

Use a safety pin to pull the rubber band through the created tunnel and mark the correct width after trying it on. Then sew it overlapping with a straight stitch to form the ring and shorten the ends. Close the feed opening with an elastic stitch.

Cut a piece of SnapPap (height 3 cm, width as desired plus 1 cm seam allowance) and decorate it. Here I ironed on and patched up a patch. Fold both seam allowances backwards and sew them on the back of the waistband. This fixes the rubber band so that it cannot twist. You can also place a vertical seam on the waistband at the side seams.

Hem pants legs

Check the length of the pants. Then fold the hem edge around your hem allowance, iron the hem and topstitch it with a twin needle.

Alternative processing variant for the federal government

For the alternative waistband, you can use a decorative rubber band. The width can vary because it is used without the collar cut pieces. You only cut the trouser legs and pocket parts with this variant.

Place the elastic around the child’s stomach. It shouldn’t be too tight or too loose. Mark the length and add a seam allowance at both ends. Close your elastic band to form a ring and fold the seam allowances outwards. Stitch the seam allowances.

First mark the quarters and then the eighths of your elastic waistband and your waistband so that you can easily put them together later. Place the elastic band in your pants evenly stretched left to left. Choose a suitable thread color, as the stitch will be visible later. Sew the waistband around with an elastic stitch. Since you have to stretch the elastic a little while sewing, it is best to support the fabric transport with your left hand and, exceptionally, push your material slightly under the presser foot.

Cut back the seam allowance of the pants (only the jersey, not the rubber band!) So that you can no longer see them later.

Finally, fold up the elastic band and quilt the seam allowance just outside the edge of the rubber band with an elastic stitch from the outside. Again, you have to stretch the rubber band a little.
