Learn how to make an infinity sweater scarf by upcycling a sweater! Use a soft sweater to make it cozy for this beginner sewing project!

I always need a warm scarf on cold winter days. I love wearing them inside to snuggle or outside with my warm coat. I love infinity scarves because they are so easy to wear (and make)!

I made a couple of different things out of this specific sweater, but I think the infinity sweater scarf is my favorite. Upcycling is satisfying, and it makes sewing a gift cheap and easy!

As you can see my sweater had already been chopped a lot before starting this project. You will most likely be starting with a full sweater.

sweater to upcycle

Start by cutting the sweater into a tube by cutting across from armpit to armpit. Then cut the ribbing off of the bottom.

Cut the tube into a rectangle by cutting through one side seam.

cut sweater rectangle

Fold the rectangle if half lengthwise with right sides together. Sew the long side with a serger or a zigzag stitch.

Turn the tube right side out.

fold right sides together and sew

Line up the short ends with right sides together. You will be sewing the edges together, but you won’t be able to sew the entire seam.

pin short side right side together

Start at one spot and zigzag the edges together as far as you can go before it gets to close to where you started.

sew as much of seam as possible

Pull the seam inside the infinity scarf. There will be a small hole still open.

turn right side out

Either handstitch or topstitch the hole closed. Hand stitching looks a lot nice, but topstitching is quicker.

You finished. You can wear it with one loop around your neck or you can wear it by doubling the loop around your neck.
