When we got married we received a gorgeous duvet cover off our registry and retired our hand me down comforter. After we bought our house, we used that comforter in our guest bedroom as a quick solution to a room low on our decorating priority list.
It's a good comforter, just too dark for my taste. Once we got settled, I wanted to add a little decor for our guests and brighten the room up. Comforters are SO expensive though!
That's when I found the duvet covers at IKEA. One duvet and 2 pillow shams for $29.99. I wasn't sure if I could use the duvet over the existing comforter but I'm cheap and wanted to try before spending money on a filler comforter.
It fit perfectly over the existing comforter and you can't even see the old pattern through the white bits. Just another reason I love IKEA!
