This stuff is FUN.
Use it with a stencil, or in this case a doily, and smear it on with a piece of cardboard. Lift off the stencil and VIOLA- a raised surface that hardens up quite nicely.
I tried it out on a tag I recently did and am looking forward to using it on some other valentine projects. It adds such a neat texture. You could use it to make your own faux raised wallpaper remnants that seem to be so popular these days.
Another little tip: the seam binding on this tag is originally off white. I watered down the acrylic I used to paint the tag and sponged it on the binding to make a custom colored ribbon.
