HELP! AFTER DOING A WEDDING CAKE THIS WEEKEND I NOTICED RIDGES AND CRACKS IN MY ICING AFTER IT SAT OVER NIGHT!!

I COVERED SOME UP WITH THE DECORATIONS ON MY CAKE! BUT I WANT TO PREVENT THIS FROM HAPPENING AGAIN! ANY ADVICE WOUD BE NICE!

Not exactly sure w/o seeing pix of it but sounds to me like you had too much liquid in the recipe &/or it melted some. Is it hot &/OR HUMID where you are?

Just for your info: it is considered shouting/rude to type in all caps.
