I wish I knew! I am very tactile person. When I'm in a clothing store I touch everything. I haven't ever bought sheets based on thread count since I am not rich. :) But there is part of me that would *love* to have the ultimate in bedding comfort. I have stayed in some pretty awesome hotels that had the most amazing sheets ever so I'm assuming there is some truth to the thread count rumors. Some day I will buy some 400 thread count sheets and I'll let you know.
