Candy cane - what to do?

One side of the stocking has a tree; the other side has a candy cane. The tree lends itself nicely to intarsia but the candy cane is only 2 stitches wide in most places and striped at that.

I could (if I had done it earlier) purl the stitches of the cane and duplicate stitch them after. Or I could duplicate stitch then on knit. Or I could crochet them either way. Ot I could make the candy cane and then sew it on. Hmmmm....
