I too was noticing that the pattern was not the same as the picture in the blog. I have done them both.
For both you make your strata - mine was 2.5" strips, four strips going from dark to light, made a 10" strata.
The quilt in the pattern is done with the 60* triangle.
The quilt in the blog - the strips are sewn the same way, but then you cut the strata into 10" squares.
Lay one square down, face up, with colors going light to dark.
Lay another square on top, face down, with colors going dark to light.
Then cut a diagonal through both squares. (always cut the same direction)
If you keep them just the way you cut them, Sew on the diagonal of each stack of triangles. Like making HST.
When you open them you will have two different blocks. The same, but reversed colors Alternate the blocks to make the design.
Hope this is clearer than mud!! Good luck, Ann.
