This looks like a classic diamond quilt but is made with simple triangles. A 60 degree triangle ruler at least 6" is required, although a template is included the ruler is highly recommended.
I'd call this an intermediate pattern due to the accuracy required to line up the units and the seam allowance has to be exact. Once you've got that down though this pattern goes together really fast.
Step by step photos and diagrams of block construction are included in the pattern.
