I've been making a lot of cupcakes lately, and my decorating is only so-so. When I pipe on frosting with a round or star tip, I end up with a mountain of frosting that is waaaaay too much (see first image below). I'm looking to learn how to make the frosting on top "flatter" so that it's still a swirl, but not a huge, overpowering mound of icing. (see second and third photos). I also want to learn how to do the piping in the final photo, which I guess is done with a frosting knife.
Are there any videos that will show me how to pipe on icing correctly? I've looked all over the internet and the ones I've found are terrible!
