Maureen -- I agree, Prism has great instructions. I find if I am very careful to make sure the folds all line up (sometimes the inner fold is not perfectly in line with the outer fold) AND I line loose ends exactly AND I make sure the side closest to me is straight (I use the lines on the cutting mat) AND I make sure either my ruler or shape cut is straight on the side closest to me, I can cut straight. If I get sloppy and skip one of those steps, I regret it. It takes longer, but then every inch of the strip is usable -- and don't we pay for the whole length?
