I made a volleyball graduation cake last year and used 1/2 of the Wilton ball pan. I frosted it with buttercream and used mmf over that (very easy, never had used it before). I then used the pattern included with the pan and placed it over the cake. I then lightly pressed, you don't want to rip the fondant, with a fondant tool to make volleyball indentations on the ball. After removing the pattern I pressed more firmly to make deeper impressions on the ball. I let the impressions set ( several hours) then I used black frosting coloring (diluted)
in the impressions to make them more visible. I have to admit it turned out very cute. I just place the ball on one of the corners and decorated alittle more and it was perfect. Sorry I don't have a pictue though.
