I was super excited about these sheets and when I got them I couldn't wait to get them on the bed! 600 thread count....please! I unpacked them and ran them through the washer on a short regular cycle and much to my dismay I found that many of the seams had started to fray. For me it was worth it to pull out the sewing machine and run them through for extra reinforcement but if you are not handy....this might not be the purchase for you. All of that being said......they DO FEEL GREAT!
