Oh and one more thing. When I cut the foundation peice, I then took my ruler an placed it in the left hand corner and went straight to the opposte corner (with a pencil),and my first piece I placed on the line and just kept going. When I got to the end of one side I turned it around and did the other side, I laid all strips out before I sewed so I could adjust the colors if need be and thats how I got the lines so straight. Sorry this is so lengthy I NEVER had anyone ask me how to do a pattern. New to explaining.
