I did one in January. I actually used the 1/2 of the Wilton Sports Ball Pan, lightly crisco and corn starch the inside, roll out grey gumpaste about 1/8" thick, place inside of bowl, cut neatly around the edge so it is clean. Let dry overnight. Then in the morning I moved it around to make sure it wasn't sticking. And let it dry a few more days. Then add accents and airbrush silver. Hope that helps!
