Ideas from a Facebook poster for making Go sets:
ideas for cheap stones:
1.small buckles. they are sold in large packets in shops in the center. I'll check prices and write back.
2.actual stones collected from the beach. it's not hard to find black, white and red stones in appropriate size.
3.tops from water, soda or beer bottles. many people collect them.
4.different kinds of dry beans. a packet should be enough for the ten go boards!
- all of the above. not all go sets need to be identical... )
