I did mine with an odd number of stitches.
1) for the "setup" row, I did K1 wrap K1 wrap K1 wrap K1, ending with a K1.
2) the next row is K1 drop K1 drop K1 drop K1 and so on, ending with a K1.
the wrap is simply wrapping the yarn around the right needle once. it's done in the same direction that you wrap the yarn when you do a knit stitch.
the 'drop' is just pushing 1 loop off the left needle.
in the attached pic I wrapped once per wrap. for wider drop row, wrap twice. but if you wrap twice, you would push 2 loops off the left needle every time you 'drop'.
sorry if that's confusing - if I could show you in person, I would.
HTH, even just a little. :D. good luck. :D
