Wrapping Paper – There are many types of holiday wrap organizers available at the Container Store. You can also purchase a rectangular plastic bin that can hold your wrapping paper. Then you can store the wrapping paper container in your storage unit easily with your decorations after the holiday season.
Bows – most important when storing bows for gift wrapping is not to crush them in storage. The key is to use a box or bag large enough to offer air cushioning. For example, using a large zip lock bag would be effective after making sure there is enough air in the bag to keep the bows from being crushed. Think of a chip bag, and how the air allows for you to open the bag to chips that are still intact.
Ribbon – The Container Store has a specific ribbon storing box available. If you would like to store the ribbons yourself, great places for the ribbon include small boxes kept with your wrapping paper and bows.
Holiday cards – if you are the type that likes to hold onto the many holiday cards you receive around Christmas, then using a box with dividers representing the year would keep you organized.
