The phrase "velvet pumpkins" is an idiomatic expression that means something is very easy or effortless. It's a metaphorical comparison between the smooth and plush texture of velvet, which suggests comfort and luxury, and the round shape and bright color of a pumpkin, which symbolizes harvest time and abundance. The phrase implies that achieving success or completing something is as simple as carving a pumpkin - it may require some effort, but ultimately it's not very difficult.
