Maryhill and the pre-strung Zentangle® Zendalas. Both of these used the same pre-strung tile pattern, and in each I chose to add to and ignore some of the string.
For the first tile, I went with smaller segments and my lines were closer together. While I do really like it, it's a little busy. I decided with the second that I would use larger segments and space the lines further apart. I thought I'd share how the second tile evolved.
