Coil Tangle

Here is another simple tangle. It also can be customized with other designs or shaded in a variety of ways once you are finished with it. The video is great instruction and is easy to follow along with. 

Zentangle Betweed

This is another "tangle." It is called a Betweed. It's simple to do, yet looks very neat when you combine it with other doodles or tangles. The instructional video is below. You just might be tempted to follow along on your own tile or feel like getting out your materials after watching it! Very inspiring!
