I greatly appreciate all the input/advice anyone can give me. I really don't like being a beginner again.
The amount of filling depends on you...as well as it being close to the top, is where you put it. You have to insert the Tip down below the middle, start sqeezing and the more you squeeze in the same spot is how you get its thickness and as you squeeze you are pulling up. Stop squeezing when you pull the tip out of the Cupcake. I like a good amount of filling in the cupcakes but Hubby likes barely there or none at all.
This might be too late but have you tried using a small dab of royal icing in a complimenting colour.
