Seriously, you have never used Christmas stuff as or on clothing? It is really a lot of fun and cheap.
Back to the tree skirts - I was shopping at Walmart after Christmas and thought I would look at the decorations. My color scheme is black, white, silver, and gray and sometimes I get lucky. That year Walmart carried a line of black velvet tree skirts, stockings, and ornaments. And, yes, I managed to clear the aisle when I tried on the black velvet tree skirt.
Not bad for a quick Victorian mantle - and no sewing required.
Here is my other find - this time at a Garden Ridge Pottery for $1. I have added the purple trim (reclaimed from another garment). I love the peacock colors and the hint of feathers in the back view.
