I get an aching back and arms just from painting a ceiling in one solid color. I can't imagine how it'd feel to paint one in a gingham pattern. However, the results look worth it:
Really, though, it seems these examples are either wallpapered (as in the second image) or painted on canvas which is then applied to the ceiling (as we read was done in the first image).
While gingham is usually country and a little dowdy, put it on the ceiling in a vibrant shade and it's suddenly a fresh pop - perfect for spring! What do you think?
