A tessellation is a repeating pattern of one or more interlocking shapes that cover a surface without gaps or overlaps.
A nation is a group of people with a common geography, language, culture, etc.
Tessellation Nation is a collection of tessellations with a common origin: a tile of my own design.
My name is Raymond K. Houston, and I am the author of Tessellation Nation.
Many years ago, I developed my own method of designing patchwork quilts using the operations of symmetry and a simple square tile. I taught this method online at Quilt University; I demonstrated this method on HGTV’s “Simply Quilts”; and, I taught this method as a workshop to quilt guilds across the country.
More recently, I revised and expanded my method. I settled on one single tile to work with and I changed my definition of a block to include symmetric and asymmetric arrangements. I realized many of the patterns I generated were actually multiple-shape tessellations. I discovered ways of combining these shapes to make new, interesting tessellations. I wanted to catalog my endeavors.
Tessellation Nation is my online catalog of patterns generated from a single tile.

Greetings Raymond,
I am not sure how I came upon your site, but glad I did. Your tessellations are really exciting. I’ve never been that excited about patchwork until now. I think I may attempt something small in the near future. Thank you for shining a bright light!
Peace & Joy,
