The outline has been completed in black stained glass. As stated in a previous post, it’s important that you have a good amount of glue on the outline. In this case, there is excess glue after laying down the tesserae. You see gold Van Gogh for the interior of the dragon, and red for some of the background. Because red, gold and black are bold colors, I am considering a rich blue either as part of a double border, or in the background in some capacity.
