I used to work as an interior decorator. It always made me sad when some women wanted to throw away beloved items because they didn't "match" their new Tuscan kitchen. I think that pops of individuality is what makes a house look like a home, instead of a magazine page. In fact, if you look at decorating magazines, there is frequently something in the room that makes it less matchy- it pops the decor.
I think you should have what you love around you. Just like the quilt police, you need to ignore the interior design police. Bland is not always the way to go.
