This photo (which I found nestled in an Airbnb listing for a funky cabin in Idyllwild, CA) may just give you some inspiration for pimping out your deck chairs.
If you're thinking about making your own custom seat cushions, think about buying extra fabric (I'm REALLY digging the fabric used on these) and some foam, or other stuffing materials, and create a matching foot rest! This is a total deck-lounging upgrade.
Has anyone attempted to make one of these puffy foot stools? Any tips for the Homies?
