Out of necessity, we recently bought a new bed cover--
I've been having a terrible outbreak of skin problems (eczema/allergies) for the past 6-8 months, and it's recently ballooned out of control. Over these last few months, I've rid my closet of all clothing that is not 100% cotton (and, unfortunately, that meant giving away some of my most treasured articles of clothing).
Since the problems are still persisting, we switched our 100% polyester bedding to cotton, as well.
It hasn't solved all of my problems (hopefully it's helping), but it's a fun change in the decorum.
Besides, it seems to be a big hit with the kitties (though that's not helping matters either)!
