I have decided that my next challenge will be tube settings. I want to use 2mm stones (going up to 3mm stones) initially, to decorate my work. I have bought some tiny stones from kingsclere, mostly faceted and some cabs too. I also have a range of ball burrs but i might have to buy some setting burrs too. I'm going to try setting just with my square bezel pusher. Any sage advice before I set to work. Particularly like to know where you buy your tubing from.
