I love zentangling! It has really helped me cope with my chronic pain. Actually, what I do is zendoodling, as l use recognizable organic shapes such as leaves and flowers in mine.
Call it what you will, l find it fun, inexpensive and easy to do anywhere. It recently helped me pass an extended airport delay, lol. I carry a small plain notebook in my purse, as well as having a folder l carry with me when l expect to be waiting a lot.

Love it and have taught all the grandkids to do it also.
You can also zentangle using thread and your machine, not as relaxing but love it.

madamekelly,

Here is some inspiration for you from Bernina's German blog:

I often don't even bother translating these pages -- the pictures speak for themselves.

I have done some and have a couple books but not real fond of the combining of different tangles or creating art. I do mine on a 3x3 post it note pad. It is the pattern that fascinates me more than all of the shading.

Some good ideas for filling those white spaces in a quilt!
