Great little book. I use it to keep track of the diffrerent types of Zentangles. An idea that came via Linda Farmer and it worked out really well. Just as she said it would. The squared pages has made it easier to dissect the Zentangles. Plus I love the cute factor because it's tiny (3.5 x 5.5). Easy to slip into a purse. Some people might fill the pages a lot faster than I have. And if you are a person who Zentangles continuously you might want a larger size. Linda said she filled hers quickly and decided to move to a larger (5 x 8 1/4 inch.) one. I love the tiny size. I might move to a larger size later but right now this works great for me. I personally think this is a great try me size.
