Things You'll Need
Size J or K crochet hook
Medium weight yarn
Many types of clothing, such as sweaters, ponchos, skirts or pants, can be crocheted. Crocheting a pair of pants is simple but time intensive. These pants fit someone with a 34- to 36-inch waist, but increasing or decreasing the size is easy. Anyone is capable of completing this project so make several pairs of crochet pants for yourself, gifts or for selling online or at craft shows.
Cast on the yarn by wrapping the yarn around your crochet hook. Catch the yarn with the hook on the side facing the yarn skein. Pull it through the loop on the crochet hook.
Add chain stitches by catching yarn, facing the yarn skein, with the crochet hook. Pull the hooked yarn through the loop on the crochet hook.
Make a treble crochet by wrapping the yarn around the hook, then sliding the hook through the desired stitch. Repeat this step twice, then pull it through two loops on the hook. Pull the yarn through the loops twice, before pulling it through the remaining loops on the crochet hook.
Form a slip stitch by sliding the needle through the stitch you want attached, and catching the yarn on the side facing the skein of yarn. Pull the yarn through the stitch and the loop on the crochet hook.
Cast on the yarn, and make 36 chain stitches. Measure the length of the row. Add or remove stitches to make the row exactly nine inches.
Chain two more stitches, and make a treble crochet into the chain stitch closest to the crochet hook. Make a treble crochet into each chain stitch across the row. Make nine more rows following this pattern.
Form the crotch of the pants by making eight chain stitches, and put a treble crochet into each chain stitch. When you get to the treble crochet stitches from the last row, continue making treble crochets across the row.
Make two chain stitches, then put a treble crochet into each opening on the row below. Follow this pattern until the leg measures 27 inches from the crotch. Cut the yarn, four inches away from the last stitch, on the side facing the skein of yarn. Pull the yarn through the last stitch, and weave the ends into the stitches on the leg panel. This completes one leg panel.
Create three identical leg panels. Once you have all of the pieces ready, start assembling the pants.
Assembling The Pants
Lay one of the pants panels on a flat surface, with the crotch area facing right and the bottom of the leg facing you. Put a second panel on top of it the same way. Pin the left side together.
Thread the yarn needle with four feet of yarn and tie a knot at the end. Slide the needle through the two panels at the bottom of the leg on the pinned side. Pull the needle and yarn almost all the way through, and slide the needle through the knotted end of the yarn. Sew up the left side of the leg. When you get to the top of the leg, push the needle through the edge of the left side of the panel, then wrap the yarn around it twice. Pull the needle through the wrapped yarn, so it forms a tight knot. Cut the yarn by the needle and weave the ends into the pants.
Sew the right side of the leg panel from the bottom to the crotch. Leave the area from the crotch to the top of the pants open.
Lay the remaining two leg panels on a flat surface. Pin the legs and sew them, just like the first two leg panels.
Put the two sewn leg panel sections on a flat surface with the legs facing you. The crotch section of each panel should face each other. Pin the top and bottom two panels together. Sew the waist area on the front and keep sewing all the way through the crotch area, until you reach the top of the waist on the back.
Weave a piece of stretchy, decorative cord back-and-forth through the openings in the top of the waist, starting at the center of one side. Once you return to the front, test the pants on the person you are making them for. Pull the stretchy cord until it is comfortable. Tie any kind of knot in the cord, so it stays in place. Thread a bead on each end of the cord hanging down, and tie any kind of knot on each cord.
Increase or decrease the size of the pants by changing the waist size. If the person's waist is 30 inches, add two inches, and divide it by four. For a pair of pants with a 30-inch waist, make the first row of chain stitches eight inches long. If a person has a 42-inch waist, add two inches, then divide by four. For a pair of pants with a 42-inch waist, make the first row of chain stitches 11 inches long.
