A friend of mine has just sewn a fabulous wrap, and on seeing a photo of it, I was inspired to write a knitting pattern (OK, I should really finish some of the WIPs, but this was soooo quick)
I used a novelty yarn - "1 hour scarf", which is sort of a stable chenille. It is unusual in that a stocking stitch does not roll at all at the edges. I am not sure if you can see in the photo that the wrap has quite a strong diagonal top edge.
This took an hour and a half to knit. I am writing it up for the shop!
I am also knitting another version in purple Del Sur.
My daughter "borrowed" this one to wear to dance class, and I haven't got it back yet.
