Hello, it's me again!

Thanks to the wonderful members on this Board, I found tutorials etc on making a granny square block. I only want one block (for a sampler) not a quilt. I made the block in the photo below this afternoon.

I made up a a couple of blocks like this, but one finished way too small (6.5"). The next finished too big! Setting it on point makes it hard for me to do the math....

I need 41 squares and have no idea how big they should be. Sigh.

The block needs to finish at 12.5 inches (will be 12 inches when sewn into quilt). Can someone tell me how to figure this out?

Thanks (I have just purchased EQ7 but I am still working on the beginner tutorials....)
