I know you said cotton but cariloha in philipsburg around 12 front Street has bamboo which are heavenly!! Feel like silk. <img src="http://www.traveltalkonline.com/forums/images/graemlins/Thumbsup.gif" alt="" />
The Cariloha sheets have a lifetime guarantee. Owned ours for five years and they replaced them for free when they got a rip in the seam. Most comfortable sheets we have ever had. Have bought a pair for every bed we have and have had a dozen friends buy them.
