Curtains at silk make your space feel cozy and can help block out the light so you can sleep better. I am constantly on the lookout for new curtains because I like switching things up. Right now, our living room has blackout fabric curtains that are very inexpensive but work really well (I even wrote a post about them). They were perfect while we were traveling because they block out all of the light. I also have white faux-silk curtains in my bedroom and thought it would be fun to compare the two materials and talk about their pros/cons. First off, let’s talk about what sheer cotton is. It is usually made from 100% cotton with a sheer look achieved by coating the fabric with sizing before it is woven or knit into its final form.
