This is variegated yarn, so I can't take credit for the striping. I'm not sure what color this was, but it was Hobby Lobby's I Love This Yarn. Yes, Grumpy Grandma. Crocheted mittens are very warm. When I first started crocheting, I wondered about the holes in crochet. But when I put on gloves, hats, and scarves, they actually get too hot so I have to take them off, especially in the car. Convertible gloves are nice. They're great for fishing out keys from your pockets an make nice driving gloves. You can put a pair of those one size fits all stretchy magic gloves underneath if the temps turn subzero, like it has been here for the past week or so. Toasty!
