I have tons and tons of wire shelving in my house, and very limited storage space, so I've taken to categorizing items in baskets and bins. I designed these hooked tags for myself, and then friends and family wanted them, and then.... well, you get the idea.
NOW this line of products has grown to include 3 font options, 4 material options (including dry-erase!), and either hooked tags or tie on tags.
While I don't personally have a kitchen pantry (trust me, I want one very much), I do have a wire shelved closet in my studio, and I have definitely used bins, baskets, and containers to their fullest extent to be able to easily see what I have and keep track of it. Of course, we all have a corner of our closet that ends up being a "catch all" - don't think that your storage will always look pinterest perfect - you'll still need a monthly or quarterly "check-in" - especially if you're not the only one using the storage systems!
