Hi swanrd... I cut two and a half inch strips.... then cut 2 and a half inch strips the other way, then 4 and a half inches, then 6 and a half inches, then 8 and a half inches.... it works.... don't know where I got that idea from but if you follow the picture you can see where to put those sizes... I love the pattern.... but put them together another way... as mentioned in a message up above....
