I recently was introduced to the website animatedknots.com. This site contains a huge array of different knots. Each knot is presented in a series of rotating still images so you can see each step in tying the knot. You can control the speed the slides are displayed in. For some knots they show more then one method. There is also a extensive write up for each knot discussing some of it’s uses. This is a great site if you need to brush up on your knots before you teach the girls, or if you have a tablet available, it can be used as a resource for the girls to learn. They have a really extensive collection including flag knots and lashing for gadgets. If your girls really enjoy knot work, they even have some decorate knots and other more challenging works.
