Started up like this:

CO: 6 sts
K2, yo, K2, yo, K2
Next round purl
K2, yo, K1,yo, K2, yo, K1, yo, K2

…just noticed that I haven´t yo on every round. Only on the right side. But… it looks ok, and the stitch count is 230 (I knitted the two stitches closest to the yo in the middle together on each side).
My Collonade will probably turn out a little “longer” than the rest of them, but I don´t intend to rip it. I´m going with the flow…;)
