Have you seen these beauties from West Elm?
Yes, they are Nailhead Linen Panels.
And they come in flax and slate with antiqued-nickel nailhead trim. Price ranges from $59 – $89 and free shipping. If you are crafty, you could DIY, but why would you at those prices?
P.S. Dear West Elm, please make these in white or ivory so that I may hang them in my family room. Thanks a mill, Miz spark!
spark! 
Ooooh I love those! I have white linen curtains in my living room and man oh man would they look fabulous with some nail head trim! How can I make that happen…
