Hi, to most of you this will seem a stupid question, but never having been shown at the evening class I went to, I am going to ask anyway. I understand the concept of tube setting, but not quite sure how to go about it. I suppose the easiest answer is to buy tube the correct size, but for an 8mm facetted stone it would be impossible I should think. So for making my own I suppose I would do the same as bezel setting a cab, but how do I put in the "shelf" to stop the stone going right through. Is it easier to solder on another strip of silver inside the bezel bit before you make it into a tube, or is there an easier way please. I know you can buy silver from cooksons with a cut out bit, but not sure if its what I need. Thank you in advance. Pat
