WHta tips should I use for filling and writing?...Also do I need to let the fling dry before writing on it?..I am new at cookies ..

Hi! I just made cookies for the first time yesterday. I used a tip 3 to outline and just used a spoon to smooth the filling icing in. My cookies were really big though-tiered wedding cake cutter. I used the 2, 3, 14 tip to decorate. they turned out ok. I understand now why people charge so much for them!

I used markers on them for valentines.... I wouldn't do it on certain cookies .... it's worth trying .... the royal icing has to be fully dried
