We are doing Stonescapes midnight blue with a sand tanning ledge. Thinking about adding touch of glass to the tanning ledge only. Is it worth the cost? I want it to be nice and sparkly. Also, not wanting a ton if any of the blue glass. How does the touch of glass work as far as glass colors? I like the colors of the touch of glass with sand stonescapes in the NPT catalog- It doesn't appear to have any blue like in the Puerto Rico blend. Anyone know how this works? I want the tans, black, and brown glass. Also, for a 12 inch deep tanning ledge- how many bags to make it pop? Maybe I already asked this question in a round about way above...but...does each color of plaster/stonescapes have it's own recipe for the touch of glass or are all the bags of glass separate single colors that get mixed according to customer request? Or is it just the jewelscapes they use for touch of glass?
