Just played around making a few tags that will probably end up in trades for Art & Soul. Usually there's someone in a class trading things.
The one below has a transparency overlaying the bird underneath...
and when it's down, the look changes.
You get the feeling the boy is now an angel. Has copper tape along the bottom. Trying to use up some of the overload of stash! Below another transparency over a tag. This one's a bit simpler and has copper at the bottom and some copper-colored ribbon at the top.
