How to Turn a Sweater into a Cardigan

A friend of mine challenged me to do this. If you're interested, here's how it's done.
1. Choose a sweater. This one had a low cut, making the task much easier.

2. I cut the front into half, just like in the picture below.

3. I pinned the margins and sew them using the sewing machine. But it can also be sewed by hand.

4. Find a matching ribbon and sew it where you consider best on your new cardigan.

5. And the final result.
