Now that winter is in full swing, it’s hard to imagine spring bursting from the cold, barren ground in a few months. But until then, why not create a terrarium to bring a little life and greenery inside? A homemade terrarium is an easy and inexpensive project you can do by yourself or with your kids in an afternoon. The bowl of year-around greenery, will instantly brighten a room and make the browns and whites outside seem a little less daunting.
