|Knightsbridge and Tipple|
The fun of "challenges" in Zentangle is, of course, not to pick the tangles that are your favorite but to go with the tangles given to everyone in the challenge. Tipple and Knightsbridge were two tangle patterns that I learned right at the beginning of my introduction to Zentangle over two years ago. Everyone uses them now and again.
I always think of them as "stand-bys" or "fill ins" or even as "basics". They are so simple that they are easily re-arranged and easily manipulated to any space that suits your fancy. In other words, tanglers sort of take them for granted. A staple tangle, in other words. To make them the "featured" tangle is kind of fun and different.
