I love the Grid-It system for storing my gadgets on the go, which is why I'm excited to try this DIY for myself. This gadget organizer uses the same concept as the Grid-It — flexible, elastic ribbon used to hold your tech in place — but adds a layer of nostalgia by incorporating a vintage hardcover book to keep it neat in your bag (and possibly thwarting potential thieves). It only takes a few supplies to get it done, so check out the full tutorial on DesignSponge.
