This week’s pattern is called “Ripple” and works up to about 56″ x 56″ if made as shown.

The block size is 11.25″ finished. In the picture above there are two blocks, one with a base grid of 3 (so 4.25″ unfinished squares and hourglass blocks), and one with a base grid of 5 (so 2.75″ unfinished squares and half square triangle blocks).

There is a half square triangle tutorial here; use method 2 and cut your original squares to 3.25″ for the 2.25″ (finished) triangles. There is an hourglass block tutorial here; start with 4.25″ squares to make 3.75″ (finished) hourglass blocks.
