After completing the round with the crossed stitches, knit one more round with Red.
Drop the Red and pick up the Orange (O) yarn.
With O, purl 1 round, then knit 1 round.
Drop the O, and pick up the White (W) yarn.
At this point, you may break off O, leaving a tail long enough to weave in.
With W, knit 2 more rounds.
At this point, you may break off W, leaving a tail long enough to weave in.
With R: k1 *sl 2, k2; rep from *, end with sl 2, k 1
Work another round in the same way.
It will look like this, with the red stitches being the ones that were just knit, and the white stitches being the ones that were slipped.
Next round: *RC, LC; rep from *
The RC (Right Cross) will be worked exactly as in the previous post (although in this case it will be a White stitch crossing over a Red one.
The LC (Left Cross) is worked as follows.
Place the tip of the right needle behind the first stitch on the left needle and insert it purlwise into the second stitch.
Slip that second stitch off the left needle onto the right one. As you do this, the first stitch on the left needle will drop off to the front.
With the tip of the left needle, pick up the dropped stitch.
Then slip the first stitch from the right needle back onto the left needle. The two unworked stitches are now on the left needle with their position reversed.
Knit these two stitches - LC completed.
Complete the round by working a RC, then a LC, then a RC, then a LC and so on to the end.
