One of the new books that I recently purchased is the book 'Zenspirations' by Joanne Fink. It's not strictly a zentangle book but uses the patterns and tangles as a jumping off point to create many more wonderful things. I decided to do the letter R on a tile for my new granddaughter. I even found a frame that will fit it nicely. I may add color later but I want to get my daughter's input before I do that.
