A few years ago for a relief society party my Grandma made these adorable Valentine Trees for centerpieces. What she did was spray paint (my fav) twigs from her backyard. Then plastered, them into a painted and decorated clay pot (she decorated the pot with paint and heart stickers). You could even use a piece of foam if you dont have plaster. She then covered the plaster with moss and decorated the tree with ribbon roses and a sweet bow. Making for a cheap, absolutely fun, table decoration for her party. My mom still displays this one on her entry table.
