We've always loved the idea of glass front cabinets that expose the contents behind the doors. It gives a fun, industrial, warehouse "district-esque" vibe. Since we're not about to rip off our cabinet doors and replace them with a glass front, I think it's better/smarter to start small and discrete. What Beau and I have done is find glass jars that we use in our bathrooms to hold Q-tips and cotton balls.
I love, love, love these jars! They remind me of the old Ball jam jars used to use homemade jams during Thanksgiving and Christmas. You can literally find them everywhere. We bought ours from World Market, but you can get everywhere from Walmart to Crate&Barrel.
Hope this inspires. Happy Friday, y'all!
