Some IKEA storage solutions work excellently as pantry units. Like the STUVA, fitted with a few GRUNDLIG drawers or baskets. Being able to see through the baskets is helpful in checking your inventory.
Use the KNUFF magazine holder as door bins to hold bottles, boxes of cling wrap, foil, etc against the kitchen cabinet doors.
Increase the functionality of old kitchen cabinets by modifying them to make smarter use of space. If your cabinets are short on shelves, add wire baskets and plastic containers to keep the contents neat and well-organised.
