Here in the UK I do put a few things out for autumn, mainly in my kitchen and dining room. I have a leaf table runner which I use on my dining room table, and some leaf shaped T light holders with a matching tart warmer - these go on the hearth. I have a leaf shaped plate which is filled with small fake pumpkins, and a vase which is filled with slik leaves.
In my kitchen I have a Yankee Autumn jar candle with a stay on topper which is decorated with pumpkins and gourds, this is on the window sill. I also have a wonderful tart warmer in the shape of a pumpkin.
Maybe next year I will expand this into the living room but at the moment it is in dire need or re-decoration so I'm not too bothered with it.
