Here's a great DIY fall wreath that will cost around $5.00
I started with a piece of cardboard cut into a square. Paint your cardboard ( I didn't and wish I had) a fall color. I hot glued dollar store fall leaves to cover the front. The wreath is super light, super cute and super cheap!
Last year, that is all I did to my wreath. This year, I cut a foam pumpkin from Michaels' 50% off bin in half and glued it to some brown paper (burlap would look way cute too - I just didn't have any) and taped it to the back of the wreath. I really like the way it turned out. If you don't want to do the pumpkin, it should cost only $4.00!
