It must be the weather. How can sub-zero temperatures not make you creative? Ergo, you have Finnish design. The aforesaid weather can also make a warm-blooded person from the tropics very, very homesick. Which is why, on a gloomy winter’s day in Helsinki, I picked up this nifty postcard (yours for €12), which, with a little hard work, transforms into a loping three-dimensional avatar. The reindeer rang in some much-needed X-cheer on that cold day, but I didn’t have the heart to post it. Anne Paso, who designed this postcard, also peddles postcard pigs, birds, rabbits, trees, even Moomins. See lovi.fi and slaver.
