I am attempting the Lillian Tank Top and am confused with the lace pattern. I think my error is coming from the YO portion. How do I YO after a purl stitch when the yarn is already in front? I used the right number of stitches in the first row of lace but second row of lace then I had 4 remaining stitches.
pattern: p1, YO, k4, sl1, k1, PSSO, p1, k2tog, k4, YO *repeat
