Can I ask you, what type of foam do you typically use to make your decor, and where do you typically buy or order it from? Do you use just plain white styrofoam, the green polystyrene, foam insulation, or some type of thicker foam board?
I've made quite a few of these for my own enclosures and would like to make some for my friend's enclosures, but I've always been shocked at how much plain old white styrofoam costs! I have a friend that wants me to make a background for his 40 gallon breeder tank so I went to Walmart thinking they would be cheapest, and was absolutely floored when I saw that a 1/2 inch thick piece of white styrofoam that was like 24"x16" cost almost $8! They didn't have much, and what they did have was ridiculously expensive. So I went to Michael's and they had an entire aisle of both white and green polystyrene, but they were just as expensive! The grout and the ModPodge is less expensive than the styrofoam!!!
