They're terrible. They shred to bits. Before I wash them I have to vacuum them so as not to clog the washing machine or dryer lint trap. My Dad says you get what you pay for with paint. I found this to be true with sheets.
So, I bought some newer sheets: $60 at Costco. They are so nice. I prefer the color over the chipper BB&B sheets, and they are the perfect friction coefficient--not too rough, not too slick, but just right. They're probably the equivalent of the $100-120 sheets at BB&B, and I am so happy. So really, if you do the math, I spent $75 to get the sheets that I was eventually satisfied with. Not a bad price, considering.
The experience of shopping at Costco was much better, as well. Costco makes decision-making easy by narrowing down the choices. In the sheet section, there were only 4 colors to choose from and two styles. It only took me 5 minutes to decide (as opposed to 45 at BB&B). Check out www.addictedtocostco.com if you need validation that you're not the only one.
So, word to the wise: buy the good sheets. You spend a lot of time in bed, might as well make it comfortable.
