#4 below shows the last sc completed and the next st is the flat ch lp from #3 above.
B. END OF RND: When the last st of the rnd is worked (the next st will then be the pulled up flat ch lp), cut yarn leaving a 6″ tail. Pull thru lp on hk maintaining st gauge (#4).
Thread yarn needle; insert needle thru/under both lps of 1st sc st of rnd, then insert needle into ctr of last st of rnd thru to the wrong side and under the additional horizontal st; do not twist st (5&6). Then:
