In this instructable, I'm gonna tell you how to make this scarf with your hands as only tool.
It can be a little tricky when you've just started, but after a few minutes you'll notice how easy it actually is.

Step 1: How to Start

Make a slip stitch and put it arond your little finger.
Then, weave the thread as shown in the pictures.

Step 2: Making the Scarf

Take the bottom thread of your thumb and pull it over the second thread, of your finger.
Repeat this for your other fingers.
Now, weave again, so each finger has two threads on it. Then, repeat the last step.

Step 3: And Repeat and Repeat

Keep repeating step two untill you like the length of your scarf (or untill you're out of yarn)

Step 4: Finishing the Scarf I

Now, you need to get it off your fingers, the easiest way is to follow the pictures.

Step 5: Finishing the Scarf II

Take the last loop and pull the rest of the yarn through it. Knot that together.

Step 6: Wearing the Scarf
