I'm the first to admit that my style is quite feminine. I feel for my husband sometimes, living in a house with four females! He fixed up some beautiful old drawers recently for our room, and we're trying to decide on some 'manly' handles for them, that will still fit in with the rest of our room. And he won't let me put anything 'flowery' on top, so I have decorated with a few of his 'man' books and some photos of our girls.
Following is the Berlin apartment belonging to artist and illustrator, Olaf Hajek. It's cool, stylish, and 'manly'. I'm taking notes.
