Doesn't this pillow simply scream "summer"?
Offered by Am-sterdam-based Etsy seller Absoluut, the 20" x 20" pillow cover is made from vintage fabric and has a zipper closure at the back.
Just looking at it makes me happy. After all, what could be more cheerful than these citrusy colors and gleeful retro print? Even more grin-inducing is the price: $25. Now that's what I call "anti-depressive decorating."
