Tangle Patterns

This is one of my favorite tangle patterns. I found it through this woman's blog, where she calls it "cockles and mussels" and have used it both plain and with patterns on the circles, like the illustration below.

I really love making beach scenes out of simple shapes and using this pattern as the sea bed or shore.

In my most recent doodle (here), I used cockles and mussels for the star shape, then the pattern I used in the heart was Opus, found here.

I browse for most of my tangle patterns in Doodle and Zentangle books and at TanglePatterns.com.
