I took plain terracotta pots and added a few coats of white paint to them. I bought some wooden letters at the craft store and painted them red. Last year, I used hot glue to attach the letters to the pots. It didn't work too well. This year, I got smart and used gorilla glue. They are still attached so I will take that as a good sign.
I was going to purchase some small fake Christmas trees to place in the pots but they were $12.99 each at the craft store. Even with a coupon, I just didn't want to spend that much. So, I took a stroll around my yard and found a bush that looked Christmas-like and I pruned it a bit. I seriously should know the name of the bush since I majored in Plant Biology. I think it is some kind of holly. All I know is that it is REALLY sharp.
I cut a few sprigs and put them in vases and set the vases inside the pots. I filled in the space in the pots with soil. You can use any filler you want...mulch, wood chips, pine cones would even look nice. I used soil because it was what I had on hand.
This project literally cost me zero. I think it looks very festive. Now if I could only get those lights up the outdoor decor would be complete.
