The only holidays I really decorate for are Christmas and the fall season. I'm decorated perpetually for any Americana holiday such as Memorial Day, Independence Day, or Labor Day since I have a lot of Americana around my house, especially in my kitchen.
I was getting some interfacing at JoAnn's the other day. They had some patriotic accessories 60 pecent off by the registers.
They look perfect on our bed with our Ikea accent pillows.
