the "pattern" in question is just an ever-so-slightly upscale string quilt.
here's a
free set of instructions for the same public domain design. you can use any number of strips that pleases you; any fabric selections; any block size.

Bonnie makes hers by cutting the starting block into two triangles and then playing with sets of four. the other method involves cutting the starting block into four triangles and rotating those to get the desired effect.
it all works out the same ... except you get to keep the money in your pocket (or use it to buy fabric. :lol: )
