This winter, I wanted these to keep my house warm, and they succeeded in doing just that. I've only had them a month, but they are pilling, graying, and looking worn and dirty, and I can really notice when I change the bed. They look so nice on my bed and lock in enough warmth exactly as I intended. However, I still enjoy them, especially when the mattresses made my room's pillowcases and tiny lip appear adorable and precisely what I desired.
