Do not be afraid to mix and match my friends! You CAN mix patterns. I continue to encourage my clients to drop the word "match" and start thinking "coordinate." Same goes for furniture, wood finishes do not have to match, it's best to have different colors/finishes to add dimension.
Some of the above pillows are just pillow covers, remember that Joann has the cheapest ( in my experience ) pillow forms, including down pillows. Don't forget your 40% off coupon too!
