A few weeks ago I shared the tangle pattern I created called Onion Drops and I included a list of patterns I found that have a similar twisting feel. Many of them I had never tried out before so I'm following up with some sample tiles to see how some of those patterns work. I think I found a new favorite in Sand Swirl. You'll also notice the line work on these tiles is in color! I've been having fun playing with a pack of Stabilo pens. Usually I draw with a black 01 Micron (0.25 mm line). These create a 0.4 mm line so the line work is still fairly fine.
If this is the first time you're stumbling upon Zentangle check out my introduction to the practice here. It can be a great medium for adding a handmade element to correspondence.
