Last night after I dropped Karen at the airport I whipped up these pants in the material she gave to me, specifically for the purpose. This piece had been in her "stash" for several years! I found out that the fabric is called rayon and I have decided that I love rayon! It falls really nicely and feels great to wear. Although strictly speaking, these are PJ pants, I have been using them more like "lounge" pants. Holiday mode dictates that I "lounge" in them till around midday! lol.
