All of the dishes in my apartment have different designs. I bought them at the grocery store, or off the clearance table in the China and Silverware Department at the department store, or at the church thrift shop.
The bad thing about this is that I don't have matching dishes to set a pretty table when someone comes to dinner. But that doesn't happen often.
The good thing is that I get to choose a dish or a bowl or a cup to match my mood. Flowers or vines or pines on china--or interesting earthy stoneware--or bright orange and blue neon plastic.
I think it's kinda fun--more fun than having a lot of different shoes or purses!
