Welcome and I'm glad you found us.
Regarding your pattern, I have just picked up my knitting and tried to do what your instructions asked and can't seem to make it work. What I normally do to get a nice clean edge is to slip the last stitch of the row, and then either knit or purl the first stitch (depends on the pattern) this keeps the edge stitch from being too loose.
Can you tell me what pattern you are looking at, specifically, I'll see if I can find it and take a closer look at the picture or pattern myself.
