Laura Harms' weekly challenge (#27) is to create a Zentangle using two specific tangles: dex and vertigogh.
This is a great exercise because it may be asking you to do tangles that you might not normally do, and because it uses two tangles that you might not think to combine.

You also see it frequently in parquet flooring. We took this picture yesterday during our walk around the Hotel Providence.
Please be sure to take some time to enjoy and appreciate the many wonderful contributions to this challenge.
