My son's 1st birthday is tomorrow and I want to replicate this frosting style (and colors, I bought neon dye). I know I'm pulling a last minute by asking now, but does anyone know what tip this is?

I just bought a Wilton 4B and hope that will do the trick, any advice on that one?

Thanks so much in advance!!!!

No one knows or can suggest a nice tip to use?

I'm thinking a Wilton 6B

Thanks, I'm guessing that's a step up from the 4B? I guess I'll just try the 4B and if its really a flop I could run to Michaels. Thanks again!
