I scoured Google and found these gorgeous silk pillows from Lucy Pillows:
.....but they're sold out.
I did find these pillows from Target's Shabby Chic line, though and aside from sewing these pillows myself (I have no sewing machine), these may have to do. And at $20 for two pillows, you can't beat the price.
Do you know where I could find similar gray striped pillows?
