Wikipedia says that it is a surface with only one side and only one boundary component. Essentially is is a circle of something flat with a twist in it. I had seen Mobius knitted scarves but when Zed challenged us to make something with a twist, curls or swirls, I thought I should try a felted Mobius scarf. Sorry that it isn't the best of photos. I took it last night and photos of white felt objects are really hard for me. I started this scarf at our felting party and finished it at home. I wasn't sure it was going to work out but I actually like it and I may even wear it. I hardly ever wear anything that I make so that would be a change. It is made from the local merino I bought and is really fairly light and airy. I can't decide whether I should dye it or leave it white. What do you think?
