Each twist st only uses 2 sts - so a LT is 2, a RT uses 2. The 2 just means that it's over 2 sts, not that you do it twice so you did it right. If you P1, LT2, p1, LT2, p1 that's over the 7 sts that will be the edge. Ribbing of any kind doesn't look much like ribbing until you do a couple inches in it.
