You don't always have to look too far to find some sweet pieces that ooze with an industrial feel.
1. Get rid of everything plastic.
I mean it.
Plastic looks cheap.
If anything, grab a can of Rust-Otoleum metallic spray paint and give your 70s ceramic floral lamp a high-end metal look with a gorgeous industrial feel. You can make a lot of blah-looking things with good shape, look like a million bucks without breaking the bank.
2. Find something old and rusty. The more vintage looking, the better.
Maybe its an old street sign.
Check out an antique shop for an old locker.
Maybe you're not so handy with getting your hands dirty, but grab a buddy one afternoon who likes welding, and have them cut the front end off a 1953 Ford you found off craigslist.
Add a couple pieces of metal furniture, like these rusty barn tin ottomans.
3. Mix dark and light colors.
Paint a wall or your ceiling a dark gray or black color.
Add a soft, light colored faux rug. Visual texture is everything.
