Learn how to upcycle sweater sleeves into a sweater mug cozy. This beginner sewing project is great for keeping mugs warm, and makes a great handmade gift!

Sweaters are one of my favorite things to upcycle. There’s so many things you can make from one sweater! I had an old sweater that I wanted to make a mug cozy from the sweater sleeve cuffs.

The sweater is nice and warm to keep a mug warm, and the stretch of the cuffs keep it snug against the mug. This is a really fast and easy sewing project, and it makes a great gift!

What is Refashioning?

Refashioning is to fashion clothing again or differently. I usually use this to describe when I’m sewing clothing to fit different or to look different, but the majority of the item stays the same.

What is Upcycling?

Upcycling is to reuse material to create something better than the original. I usually use this to describe when I’m sewing adult clothing into clothing for children or I’m sewing clothing into an accessory or house item.
