If you'd like to sleep in a big cloud, here's the perfect quilt from Pottery Barn: Cloud Quilt ($249 for full/queen). The quilt is ruched cotton sateen and backed with silk habotai. The fill is polyester fiber batting.
The matching shams come in standard and euro for $49 and $59 each.
Pottery Barn's Fall 2009 vibe is "Vintage Style".
They're showing a bunch of vintage-look quilts, the style part is somewhat questionable. I guess it would depend on the rest of your room...
I've never been a big fan of quilts especially with busy multi-prints, but in the right room it could have a certain charm. I would say less is more, if you opt for a busy/colorful quilt keep everything else as low key as possible. And it's always good to keep your rooms as pared down as possible... to much "stuff" around never looks good, even if the "stuff" is expensive chachkes. One nicely placed chachke is fine.
If you just want a dash of vintage chic, I'd just toss one of these cute bird pillows ($35 each) on top of my bed with my existing pillow shams.
Cute, right? That's more my speed...
