Givio, I see the block you mention but it actually is placed correctly...see all of the stars are alternated light-dark and that one is within the pattern. Took me a while after playing with my blocks to realize each block's star corners are opposites...one light-dark and the other dark-light. This means you can make any block work when creating the four block stars as Jane has done.
Dorothy, there is a separate sign-up for the next month with the deadline in the title. Blocks are to be mailed by September 15. Be sure to PM jclinganrey to let her know you plan to participate in the September group and how many sets you'll send. Happy to have you with us!
