Things You'll Need
Knitting is the art of creating objects out of yarn by intertwining threads of yarn to create stitches. There are many different things you can knit, including a pair of underwear. Knit underwear will be very warm and soft. This makes them appropriate for the cold winter months. Creating your own knit underwear requires understanding the basic terms of knitting which including "knit" and "purl" the basic steps in knitting. "Knit" refers to putting the right needle behind the left and "purl" is when you put the left needle behind the right. Use this information to knit your underwear.
Measure the waist of the person for whom you are making the underwear. Add an extra inch or so to that measurement so that the underwear can slide on easily.
Tie your yarn to your knitting needles and hold one in each hand. Bring them close together at the tips to assume the knitting position.
Begin knitting the top of your underwear. Knit two, purl one and then knit one to create your stitch.
Repeat this pattern until you have created a circular band that is as wide as the measurement you took. Put the band on the person's waist to see how well it fits.
Continue knitting your stitch pattern until you have knitted the entire height of your underwear. You should have knitted underwear that don't have separate legs. Cut your yarn and tie it to a stitch to hold your underwear together.
Measure the leg width of the person who is going to wear the underwear and then add two or three inches to that measurement. This will be the width of your leg holes.
Pick a front and back side of your underwear and write their names on a piece of masking tape and stick it to the side.
Lay your underwear flat on a table and measure out the width of each leg on the front and back sides of the underwear. Label these spots with a piece of tape. There should be several inches between the legs.
Open a stitch up on the left leg marker on the front side and insert a new piece of yarn. Knit across to the back side and open up a stitch to insert your yarn. Knit to the right.
Continue knitting across the bottom of your underwear until you reach the other leg marker. Cut your yarn and tie it to a stitch to hold it in place. You should know have a pair of underwear with two leg holes.
