The home of the world’s largest library of tessellations from a single origin

Welcome to Nacho Grandma’s Quilts.

My name is Raymond K. Houston, and I have been quilting for fifty years.

Along the way I developed a method of designing tessellations unlike anything I had seen before.

Tessellations? What are those?

A tessellation is a pattern of one or more interlocking shapes. I have a library of tessellations that I could never hope to make into quilts.

So I’m inviting you to make some of them.

Browse the Library. Learn the Method. And if you make something — send me a photo.

Well, would you look at that.
