Powdered Sugar & Lace on a Cake

I love this idea from My Two Butterflies for decorating a cake with powdered sugar and lace. If you're low on time it beats frosting a cake, though I suppose if you love frosting this wouldn't be the dessert topper for you. I'm curious if it actually holds or if it blows away the minute you try and cut a piece of cake. Has anyone out there tried this decorating technique before?
