Ok, I'm not very good at explaining but what I think she means is
You take 4 fabrics and make 5 strip sets you then you cut those at 4 1/2" . So you should end up with a rectangle of 4 1/2 by 8 1/2 In step 1 you should have ended up with a rectangle of 4 1/2 by 8 1/2 and when you sew the 2 of them together you end up with a square of 8 1/2 x 8 1/2 [ATTACH=CONFIG]546292[/ATTACH]
