I just looked into what the puppet tool can do and it looks interesting – I just don’t know how that transforms to what I want to do.
I tried to sketch out, what I want to achieve. Maybe that makes it more clear. I want it to look like let’s say a string of wool wiggling around and forming a text. Would I create that string in After Effects or start of in Indesign or Photoshop?
Here’s the before and after image I sketched out.

Thanks for your help!
