I Just thinned buttercream to very runny consistency, then took a paint brush that had a big head(an artists brush, but I think a regular one would work too!) And flicked it toward the cake. Going in different directions around and on top of the cake! I also wanted to write on the top of the cake, so I cut a piece of waxed paper into an oval and centered it on the cake top. Once I was done splattering , just picked up the paper and finished the cake. Food / Yum / add marbles to make heart shaped cupcakes.
