Winter is coming and you CAN keep your white bedding during the cooler months! To keep it from looking summery, I suggest layering the whites with some velvet and fur to make it really cozy. Here are some inspiration pics.

Etsy has a lot of beautiful velvet pillow covers to choose from.
I LOVE this one.
And this one too! It it is only $15!
This pillow cover is pretty too!
Ikea also has some pretty velvet pillow covers for only $13!
And I saw some nice looking fur blankets at Homegoods the last time I was there.
Hope that helps mom!
