yeah, all WS rows will be a knit row.
If you look at row 2, the kfb is at the beginning of the row and then in row 4 there's a k1, kfb. So I am assuming that row 6 will be k2, kfb and row 8 will be k3, kfb, etc. So there will be one more stitch worked at each edge before the increase on each subsequent RS row. Then in the center increases, on row 2 the two increases are right next to each other (ie. kfb, kfb) then in row 4 there is a kfb, k2, kfb so again, I think row 6 will be kfb, k4, kfb for the center increases and row 8 will be kfb, k6, kfb, etc.
Does that make sense??
