lace pattern question
i am quite new to this forum, but hoping that someone might be able to explain a pattern to me. i've done gone and fallen desperately in love with a lace skirt pattern that i found in some arcane magazine! the pattern is probably too difficult for me, but that probably won't stop me from trying.
there are a few different lace patterns used in the skirt. under the first lace pattern, the very first sentence of the pattern says, "over a multiple of 8 sts plus 1". any ideas on what this could mean?
next, the first row contains a bunch of "yo twice", which i understand, but then the second row says, "purl, working p1, k1 into each double yo".
can anyone explain any of this to me? any thoughts that could be offered would be mightily appreciated.
