Not Worth It:
1,000-Thread-Count Sheets

Don't spring for anything over 400, says Pat Slaven, a textile expert at Consumer Reports: "It's almost impossible to weave sheeting more than 400 threads per square inch, so manufacturers weave six or even ten super-slim fibers as one in order to market a higher thread count. At that level, you're not getting the softness or the crispness you'd expect."
