DIY making iced branches. It does take some special ingredients (like the diamond vase filler) and can purchase from this site. I don't know if you can get it anywhere else, but these are beautiful and the prices for the filler or crystals isn't bad.
Paint Dipped Pinecones - Would make a great centerpiece with some red glass ornaments mixed in a clear glass jar! Might try this then add glitter for my Christmas tree this year cuz we know I gotta have my pine cones!
