i am making a twisted bergello. i justed sewed the first 5 strips together. it looked like to me that it was starting to bow. unfortunatly i didn't read the instructions closely. that after sewing every 2 strips together to alternate the ends. if i continue to sew them like the pattern says will it straighten out? i am taking a class on it, but don't go back until next week. my friend said she sewed hers with all the one ends even together and hers didn't bow.
