I made these mittens from old wool sweaters that I felted. I got the idea from a friend of my mom's who showed me a homemade pair that she received from her daughter.
You can make sweater mittens from any type of sweater but I chose felted wool for two reasons. One, it's easier to work with because once the wool is felted, it doesn't fray which makes sewing a breeze. Two, wool is a great insulator on those cold winter days.
I wanted the mittens to have a lining because wool can be very irritating to your skin. So I lined each mitten with fleece which adds an extra layer of warmth and coziness. For the pattern, I traced around my hand on graph paper, and then cut out a front and back for each mitten out of the sweater and fleece lining.
I also reused the sweater cuffs for mitten cuffs. I cut about a 4 inch piece off of the sweater cuff and sewed it together with the mitten and the lining. I finished each mitten off with a pretty button.
