Spotted this neat little DIY terrarium project on Design*Sponge (where else?) last week. These would make great little presents to give out to the neighbors & work colleagues for Christmas or as party favors as was originally intended by the couple who came up with this project in the first place. How eco-friendly!
Oh, I think this project would look great too if you use any ol' glass jar you may have lying around! Waste not, want not right? ;)
