I have been trying to replicate this design without success. I have tried duplicating the object and scaling it up a bit, I also tried using the FX Stroke option.
This is what I want to recreate:
Attempt 1: Duplicating the object and scaling it up a bit
Attempt 2: Using the Stroke option in FX (outline achieved, but font needs a bit of work):
I believe that they are using Varela Round as a typeface.
