I don't like hanging pictures on my walls!
I prefer family photos, wedding photos, school pictures and the like to be kept in albums rather than put up on the wall. I always think how cheap and cheesy those portraits look when I enter someone's home and they're hanging for all to see. They're never artsy or tasteful, really, and usually the person in the photo hates it. They are usually framed very cheaply and poorly as well.
I make exceptions for extraordinary photos, something of great accomplishment for instance and I do like photos from my grandparents younger days, they were always dressed so fashionably with a nice background. I like black and white and sepia tones of old photos. Still-I'd prefer those photos to be displayed somewhere wehre it's not in-your-face right upon entering the home.
I also dislike (most) paintings and most other kinds of wall hangings in my home.
I hate knick-knacks too. Hate them.
Is it normal to like overall bare walls and hate knick-knacks?
Don't get me wrong, I appreciate art and I love antiques and decorating, I do have small items, but they tend to be things like interesting clocks, vases and very, very unique and eye catching things....not a collection of ceramic unicorns or angels. I tend to use color, fabric and a bold item here and there to decorate rather than what I see is typical.
