Stuck again!

[KatherineGartner]

The round says,

*yo, p4(5,6), sp2po, p4 (5,6), yo pl,sm; rep from * to end

how do you yo when you're already purling?

[suzeeq]

A knit YO is the same as making a knit stitch except the R needle isn't inserted into a st on the L needle. A purl YO is the same - just wrap the yarn around the needle like you're purling it, start in front, go around to the back then to the front again between the needles.
