After receiving a great deal of positive feedback on the first 17th of may ribbon, I decided to make another one. I only had enough yarn for a ribbon of half the width, but that worked just fine for its intended purpose.
10 hours of weaving later, and I had 1.2m of finished ribbon, barely 1cm wide. My landlady got half of it to make a ribbon, and I used the other half to make a ribbon for myself. An adorable polar bear button from the local sewing shop made the perfect focal point, and a small safety pin attaches it to a garment.
