When I sew my pieces together on these, I started on the Left side (the open end facing me) about a half inch BELOW the tape measure "snap" piece & carefully sewed UP to the top then spin the whole piece around and sewed the usual way. I repeat it for the other side and finish again about a half inch below the "snap". My way doesn't leave any fuzzy cut end knots. This may not work for others but I like it. :)
