Hi, welcome to Knitting Help.
I would look at my work to "read" my knitting. If where I am in the pattern would require a k stitch next, I'd knit it; if it needs a purl, I'd purl it.
Do I determine pattern by looking at work to see where to pick up after K2, P1, K1, P1, Sl1, K1, psso
I think you have the idea! Nice pattern.
