Comments: This lacy little pattern practically doubles in width after blocking - as you can see, my cast-off on a 4.5mm needle was not loose enough to allow for proper stretching of the fabric. In the BW book, single repeats of this are used as an edge for a different lace panel I think it may actually look better that way. You'd just have to be really careful about measuring gauge on this when you went to work it into a project.
