It might help to state the difference between cake decorating tips and pastry tips. Cake decorating tips are mostly a lot smaller--to make this kind of swirl on a 3" cupcake, you need a Wilton #506 or #508 or Ateco tips 1A-1F or 2A-2F. Didn't see them at the cake dec section? They are sold online.
Pastry tips are a LOT bigger because they are intended to be used for dough--choux paste, spritz cookies, etc. They make really good cupcake-covering swirls because they are the right size for the job. There are different numbers for different brands.
How can you tell the diff? My rule-of-thumb is if they fit a standard coupler, they are cake tubes.
Thanks for sharing Irene. Looks like I've really got to get that cupcake icing blog movin' eh? ~ MaryJane
