Nope, I'm getting one made (by Jan at Sleeping Baby Productions in the States). I don't think that you can buy the fabric as yardage any more, it's getting as rare as hen's teeth.

There's also a similar fabric called Solarweave, which has quite a soft, woven, cottony feel to it (I have one in a Connecta buckle-tai), but apparently it's not as breathable as Solarveil.
