This is a mod of this Straw Holder/Organizer by CaesarOfSalads. I wanted a way to have the straws stand upright and not fall out. This design still works for under-cabinet storage with the added benefit of not inserting your straw(s) too far. (There are two mounting options: 3M strip(s) or wood screws.)
