Dare to be unique and mix and match designer chairs with the average vintage chair you'd find at the market. This bachealour approach is exactly the right thing to do! Then add an old rustic wooden table to complete the style! Feel free to combine all different types of chairs, benches, stools. A quick and cheap way of making your own table is getting an old slab of wood from your local woodmill and lay it on top of two sawhorses.
A tree stub can become a great stool which doesnt take up much space and gives a great unique feel. Just ask at your local sawmill or firewood salesman and I'm sure you'd get it for close to nothing.
