I'm in love with these Anthropologie headbands, but of course a knitter could never actually purchase such a thing! After studying them intently in the store (with the sales woman eyeing me suspiciously) it looks very do-able, (dare I say) maybe even easy! I think I just need to figure out the right gauge and then would knit three strips of stockinette stitch. Probably next I would bind-off each strip, then braid the three together. Then you would have to mattress stitch seam each one in order to ensure the whole thing doesn't come undone.
Hopefully I can post a pattern for this soon :)
