Thanks for all those tips! I'm "watching this topic" for reference. One thing I remember a Wilton instructor saying was to take the dam filling & after your done tiering the cake, pipe more of the BC in the outside if needed. I like the idea of letting it sit for a couple of hours but since I'm a weekend decorator, I usually don't have time to wait. Another thing I find easier is piping the filling in. I just put it in a big swirl & that's easier for me.
