newby - question on pattern
I am making a sock - I have 64 stitches divided onto 4 needles - 16 each needle. Here is the pattern: K1, sl 1 pwise, K1, yo, psso K and yo, k1... repeat. When I finish the row I have 18 stitches on the row. Is the k1 at the beginning of the pattern and the K1 at the end of the pattern the same stitch? In other words, do you knit two in a row? Should there be more stitches at the end of the row? I guess my question is this: should there be 16 stitches when I finish knitting the row?
