ISO that perfect white duvet cover

[leatherfemme]

Help?

Crisp, white, a little lacy/textured is what I'm after.

I've checked Overstock, BB&B, Pottery Barn, a few oddball sites and some/most of Amazon.

From oddball site I love this:

but the misspelling makes me hesitant to buy.

LOVE this one but not sure I want to spend that kind of $$$$

This one is great but is sold out in white...

Anybody have any other good sources or ideas?
