On a whim, I bought some tomato cages from Lowe's ($4 for the big ones). Then, I sprayed the cages RED! I wrapped the cages in lights, mesh, garland, and put a bow on top (not a fan of the bows, but I had two of them so it works). I stuck the cage in planters, but you don't have to do that necessarily.
*Side Note: other than the cages and lights, I didn't spend any money. I kinda just threw the things together quickly. I know I could do better next year with some burlap, better garland, maybe some mix of colored bulb lights, woodsy star, and twine? (just a thought) But for now, I'm happy.
