Cloud Like Boundary

Question

I'm attempting to create a line buffer or polygon outline that mimics a cloud symbology. Trying to match the red skinny arc around the thick red line.

If you configure the polygon symbology there's a Wrench icon that lets you modify how many layers the symbol has, which also allows you to add effects to each layer. If you have a "Wave effect" on the outline you can get an approximate effect, or throw in an "Offset effect" so the waves don't clip into the polygon interior. Something like this:

Keep playing with layer effects and you might be able to replicate a cloud effect better.
