I think that people tend to "overthink" paper piecing. You ALWAYS sew on the right side of the paper pattern. The first piece of your project goes fabric right side up on the BACK side of the paper pattern. Subsequent pieces are placed fabric right side DOWN on top of the prior piece with enough overlay to stich the seam, and then stiched (remeber always to stich only on the right side of the paper), trimmed, flipped and ironed. It is really a very simple process once we get over the intimidation factor. Good luck
