Simply by painting them in a similar color and finish they look like they were meant to be together!
First, another ugly duckling we found on Craigslist....a pedistal table.
We had to drive a bit to pick her up but she was worth it.
Next was a hutch I found at a yard sale. She was a steal. She had a couple of broken knobs, but she painted up beautifully.
Then they were the chairs. These were all found at separate garage sales.
They were loner chairs that had no matching partners.
They are all similar in look, so when painted they look like a matching set.
Only if you look closely can you tell they just met!
.....put them all together and you have a completed kitchen that looks like it was made to go together!
