In the era of soaring prices of homemade ladies' underwear, it costs ten yuan to buy a pair of underwear. Recently, I tried to make several main materials myself: elastic cotton cloth or tools needed for elastic lace of modal fabric: sewing needle and thread scissors, soft ruler for wiping pens. Manufacturing steps: Step 1: Cut the cloth according to the drawing, with one front layer and two crotch layers. This step does not take the second step, and the edges of the two crotch layers are aligned with those of the back piece. Sewing Step 3 When sewing, the back piece is placed between the two crotch pieces. Step four, sew the front and back pieces. Step 5, cut two elastic shoelaces about 40 cm (you can measure the shoelace ring at the root of the thigh to determine the required length). Lace and underwear are equally divided, and the pen has water marks. Step 6, locate the marked place with a pin and tighten the lace and cloth slightly. Z-stitch sewing (Z-stitch has a separate tutorial published) Step 7: Finish sewing Step 8: Sew both sides of the waist with hemming method. Step 9: Choose an elastic band that suits your waistline. I used two feet. The sewing interface is divided into four parts in step 10, the stitches are fixed, and the Z-stitch sewing is completed in step 1 12. The underwear is ready.
