My first quilt was a king size LC pieced the way E. Burns does it, I didn't need to PP, it came out super and I loved making the squares that way so much I stitched up a billion of them, enough to make my quilt, plus a double bed size plus several lap sized for gifts.
try it the ways that most interest you to see how it goes. My strips were 2 1/2" wide so there wasn't too much worry about making mistakes.
