I am doing a cake this week and would like to get some advice.  Frosting a 3 tier wedding cake in crusting buttercream.  Then piping a design on the cakes with royal icing.  Then "painting" the dried royal icing with gold lustre dust.

My question is this, once the royal icing is on the cake and dried will putting it in the refrigerator be a problem?  It won't bleed or something like that, will it?  I foresee that all this piping and then over painting is going to take me two days, so I just want to make sure there won't be any surprises.

Thanks!

You should have no problem   If there is condensation just let it dry w/o touching —maybe let a fan blow on it to speed it up   It should not run mainly because there’s so little paint involved
