I am a cotton freak due to my pruritus. Everything next to my skin is cotton or cotton-rich, as is the bedding, curtains, towels and furnishings. For the same reason I also seek out 'natural' household cleaning products and personal stuff such as shampoo and soaps. I do not mind paying a bit more for any of those and they are just as good, if not better, than some of the chemical cocktails heavily advertised on TV and in the mags.
For some reason the local glory hole has a good range of natural products at reasonable prices compared to the supermarket or chemist's so I am well served.
