Decided to make a few backgrounds for later. Sprayed some green Memories Mists over dictionary pages and let dry.
On one, used copper stencil paste over a clock stencil:
On another used light molding paste over a bird stencil. Have some extra texture, because I didn't apply the paste evenly.
On the third, used crackling paste over a dragonfly stencil. I reread the jar and it says it takes 3-4 days for this paste to "cure". It will be interesting to see what it does when I come back from vacation.
