I have the worst time finding mittens for Lubby Boy. They sell gloves for kids...not mittens. Why? Gloves are really hard to put on AND they don't keep their hands as warm. Soooo...I delved into the sweaters I love to upcycle. I'd made him a pair this way before...and I learned a few things. FIRST...Use the ends of the sleeves and make them deep...so they don't unravel and they cover part of the arm and won't come untucked.
