I have been using the 1M tip for my cupcakes and I really like it. I want to use a round tip and I have one at home but it seems to be too small. I am not sure which size it is. Does anyone have a good recommendation for an extra large tip? I am looking for the ones they use in bakeries...or Cupcake Wars They seem to have really large tips and I am having a hard time finding any in the local stores. I found a couple online...one is a 9PT. Not sure of the manufacturer. Someone said the Wilton 1A isn't very large. Please help! Thanks

Wilton 1A is a pretty big tip...

Ateco makes some very large tips, the kind you see on cupcake wars are usually ateco or another brand that I can't think of the name right now.

I got some HUGE cupcake tips at a local cake supply store they are made by Bakery Craft. I love them! They pipe the kind of swirl you see on cupcakes at DC cupcakes.

Gigi's cupcakes uses a large round Ateco tip to pipe their mounds of icing on and the large ateco star tips as well.

I bought a large round tip from:
