One of my latest obsessions is labeling everything. I'm just showing you my spice jars, but believe me, there are many more of these babies around the house.
The technique I use is simple enough. Print the labels onto full page white shipping labels (I use Staples brand). Before cutting them out, cover them in clear contact paper. That way the ink is protected from moisture. Then just stick them on.
I made the spice jar labels by photoshopping these beauties from Eat, Drink, Chic. I also stole used her idea of looking up the Latin names in an online encyclopedia. I think they look so neat and tidy lined up in the cupboard.
