Right on time this week.
Download the pattern here. (You will need Adobe Reader. You can download it at http://get.adobe.com/reader.)
Links to all the previous blocks can be found in the sidebar.
(If you want to get a head start on the sashing & border, you're going to need twenty-four 2"(finished) pinwheels. That means you will have to cut your squares 1 7/8". You will need at least 3 of each color. Directionality will be as in Block 8. Details will follow in Week 13.)
