I found a digital file from 20 years ago when I was an editor with Quilt Magazine. This is one of the images:
This is made using a center hexagon, six equilateral (60 degree) triangles and simple 9 Patch blocks. I began with 2-1/2" strips for the 9 Patch blocks and worked my way out from there.
|6" finished 9 Patch blocks using 2-1/2" strips|
My first block was sewn by the seat of my pants (and my sewing machine, btw). I created the center hexagon template (6" hexagon along the straight sides), found that the triangles can be cut from a 5-3/4" strip and started cutting. (Remember, I design with Adobe Illustrator and can create just about any block once I know a few of the dimensions.)

If you want a FREE PATTERN using 1-1/2" strips, I found a wonderful page by Marcia Hohn for making a Jack's Chain, with templates and very helpful steps, well illustrated, too. She shows steps for joining the 9 Patches with the triangles and then joining them (using y-seams) to the center hexagon. Marcia was a regular contributor to Quilt Magazine when I worked there. This is the link for Marcia's Jack's Chain.
