So, while it was still wet I flipped it over onto blue cardstock, covered it with scratch paper and burnished it with my hands. Surprisingly, it did not give full coverage as I expected, but left behind all the lines that trace the cutouts. Very delicate look.
I decided to heat emboss this with clear detail powder and the result was stunning. So much that I trimmed only enough to make it fit on the card front.
It reminded me of stained glass so I pulled out some gold peel off stickers of religious emblems and built a scene with them. This included a greeting at the top.
I used a dark yellow base card which works well with the gold stickers and embossing.
