I would suggest first getting an area rug you like and then adding pillows to coordinate with that.

I would agree with elle4maison.

Were you going to put a rug over the carpet?

I have 4-5 pillow idea books, if you would like to rummage around, only a couple are over $25. you can click my name to get there, it also lets you message me if you need help. otherwise post here and i will come back with sets tomorrow. Do you know colors, or styles, animals, florals, geometric, all black and white, birds, countries, etc
