A small pantry makes it easier to find what you are looking for. Think visibility and access. A few simple buckets (I like these from The Container Store) make optimal use of a small space. I chose these for their straight sides that don’t waste horizontal space.
(1) I start most projects by pulling everything out. (2) Check expiration dates, and send to “green waste” everything you can compost at home or see what your local city/county allows you to add to the yard trim bin (3) Dedicate the easy-to-see shelves to the most used items (4) Small items in bins like spices and condiments (5) Examine what’s left: Group seasonal items together, group dried goods like pasta and beans, what other groups do you have?
Everything else: either donate or compost/recycle.
Great idea: Put up a cork board and hang a pen on the inside of your pantry door. It’s a good place to keep your shopping list.
If you can’t get motivated to improve how you use your spaces, hire an organizer!
