I have two blankets I really like and use frequently, but I don’t like having on my bed (due to them being too warm). If I had them on the floor overnight when I don’t need them, would it damage the blankets?
Basement is always chilly (below 70F), even during summer, so I have good reason to believe it is climate controlled.
It should be OK, people put blankets on the floor all the time.
But why don’t you store them in a close during the summer?
i still use them during the summer. usage isn’t limited to covering, but also hugging.
