I have done two BOMs at my LQS that are Marti Michell's. I can not stand to use templates AND I am cheap. I go home and draw the block in EQ and paper piece them. The most recent one is based on a 7x7 grid. I draw the grid - draw the block snapping to the nodes of the grid and I am ready to sew. What is even better they are square and flat when done!
