Sometimes you're stuck with a sweater you just don't wear any more. Maybe it shrunk or became felted in the wash, or maybe you outgrew it. When this happens, there's a variety of ways you could upcycle your sweater into something new.
Do you like knitting? One way to recycle your sweater is to unravel it into a skein of yarn. This way, you can reknit your sweater into a garment you actually wear. This process takes a lot of patience, but if you particularly like the material your sweater's made from, it's well worth it.
If your sweater has become too small, you could try to upsize it by adding in extra pieces of fabric. You could knit your own, use scrap fabric, or sacrifice a second sweater to cut out panels or gores from.

Sweaters that are too big are pretty easy to downsize, too. If your sweater's made of a natural fibre, you could try shrinking it in the wash. Otherwise you'll have to tailor it. Add in darts with the ladder stitch, or resize the sides by using a fitted sweater as a template.
Your sweater doesn't have to stay a sweater! If the shoulders bother you, then remove the sleeves and turn it into a sweater vest. Chest too tight? Cut open the front and turn it into a cardigan. Top not fitting right? Cut off the bottom and make yourself a skirt or a pencil skirt.

There are many ways to upcycle a sweater. In the end, your sweater is just fabric/yarn in a sweater-shape. You can reuse it however you want. Here are some ideas to get you started:
Scarves, mittens, arm warmers, hats

There's no need to throw away a sweater if you don't wear it any more or if it doesn't fit you any longer. You can always resize, alter, or upcycle it into something new.
If you don't feel in a crafty mood, please consider giving your sweater to a friend or family member, freecycling your sweater, or donating your sweater to a charity rather than throwing it away.
