I was at the Albuquerque Fiber Arts Fiesta the other day and my kids discovered a really fun weaving/braiding activity. It is called Kumihimo or Japanese braiding. These are a great way to use up yarn scraps. Here are two results
These were made by a nine year old. Even the lower braid is very easy. It is a lot of fun. You can make your loom using foam or very sturdy cardboard. My disc is 3.5 inches in diameter. The nicks are 3/8 inches apart. There are 32 of them. While the number is not important we found it helpful to stay on track.
The upper braid is called fill the Fill The Gap. It is even easier. Here is a picture of the instructions
