I was decorating a cake this morning, so I tried this with my leftover buttercream. I kneaded enough PS into it to make a dough, rolled it out and cut it into shapes.
It worked really well. The only thing I found wrong with it was that it was really, really
sweet!! I am a sweet lover, but it was even too much for me. I guess I might use it for tiny decorations on a cookie or cake, but nothing more than that. JMHO
