what tips can you use for decorating balloons on cakes
Can you be more specific? I'm not sure what you're asking, but here's a bump. Maybe someone else can help you.
I'm not sure what you mean either. Please clarify us.
I was taught to make balloons using just an open coupler without a tip. Just squeeze the icing onto your cake and pull down to make the tail of the balloon. Then go back with a writing tip (#3 or #4) and make your string. Hope this helps.
