Important note: If your software has this option, make sure the "monochromatic" option is checked when adding noise in this instance. Otherwise, you may want to make your "gold" layer in black-and-white first (see earlier posts by Craig for any number of tips on THAT!). Also, this is an instance where the computer is a hindrance because of its inability to be "expressive" or "imperfect," so it may be necessary to start SMALLER than your intended size, and then ENLARGE and replicate a portion of the gold layer for more texture and "hole-age." Here is an earlier stage swatch
; get the color scintillation going first, and then select your best area and make like an alchemist!
