It's three year's later, and Ron's entry in Apartment Therapy's yearly Small Cool contest still pops into my head from time to time. It is THREE HUNDRED square feet. That's small y'all.
But he manages to make it feel fresh and clean and not cramped!!
Notice all the uses of outlining/borders -- on the curtains, lampshades, bedspread, walls, door, even the black and white framed photos echo it... it makes everything feel crisp and tailored. The consistent motif and limited palette is really working for him!
