It was 40 degrees this morning, so I started pulling out the winter outerwear. In with it was a wind jacket I bought at a yard sale this summer. When I tried it on & extended my arms, it looked like this: That won't do! I really love the jacket, and didn't want to have to throw it in the donate pile just yet, so I decided to extent the arms. This is great for kid's jackets, to make them last another season, while making them a little more fun. I love that you never have to search for mittens at the last minute... they are built in! Here comes the tutorial! This was a hard one to describe the steps, but hopefully the pictures will help clear up any confusion. What you'll need is a jacket, and 2 long felted sweater cuffs that go well with the jacket. First, turn your jacket inside out. Now place a cuff in a sleeve, so your cuff seam is against the sleeve. Line up the cuff seam with the jacket seam, so the seam of the cuff will be on the underside when you are wearing the jacket. Now tuck in a little bit (about an inch) of the jacket sleeve inward. Now start to sew the cuff to the jacket's inside lining. You will have to feel along as you go, so you aren't sewing through to the outside layer of the jacket as well. That way, there will be no seam on the outside of the jacket. When you are done, it should look like this: Repeat the process to the other sleeve, and flip everything right side out. Now figure out where your thumb should be, and cut a small slit there. Now you have built in fingerless gloves! fold them back once, and you have extended cuffs. It kind of looks like you are wearing a sweater under it.
