Personally, the hardest part of furnishing a house is finding the small curios. You'll never find them from day one but it's an ongoing effort taken to add new things to your collection. Colonial Soldier is a great resource for little bits of this and that for a boy's or gentleman's room. They sell old union jacks which are great for framing up to hang above beds, old soda stream bottles, antler lamps, a screen made up of matchboxes, and the list goes on. They even sell wooden toy soldiers. My favourite bits and pieces are the old bus stop sign and the radio.
