It is a Rocky Mountain Puzzle Block with directions for a 24" and a 36" version. I made a quilt using a 12" version of the block a while back and it packs a lot of punch for such a simple block.
The free download also has directions for using each block size in a quilt.
A few people have asked if I am going to continue these tutorials next year. I have thought a lot about it and have decided not to continue - they have been fun and I have enjoyed doing them, but they do take a lot of time. I do plan to continue to offer tutorials; ending this series after next month will give me a little more freedom to do different types of free projects and to work on my patterns. These patterns will continue to be available for free in my shop.
Head over to the shop to see everything that I have available:
