A friend recently told me about this wallpaper company called Calico--they make incredible handmade wallpapers based on the end papers in ancient books. They do unbelievable marbled paper BY HAND but I'm really into their ombre designs, fading one color to white to another color. They remind me of sunsets or water. There's a Swedish company (of course) called Sandberg that does a similar thing that they base on actual sunsets and sunrises--
This one is called Gryning, which means Sunset.
And this is called Skymning, which means Sunrise. I think they're ridiculously gorgeous.
Of course, this concept would be pretty easy to replicate with dyes on fabric...next round of tote bags and napkins maybe?
