When we were in Denmark last month I was happy that we just manged to go and check out the traditional 'starry sky' Christmas decoration in the main shopping (and pedestrian) street. It's about half a mile of street covered with these lights. Some of them twinkle and it's quite lovely on a dark winter afternoon and evening. It gets dark early in Denmark!
One of the department stores is always decorated with these big hearts. In a way, I don't really like them, but they are very festive and it would be strange if they weren't there.
Not actually Christmas lights, but I like the glow of the neon sign on this sewing machine shop. It has been there for decades. In a pretty prime location, so I guess sewing machine sales are fairly steady. ;-)
