Need a little help

So i am helping a deer friend of mine make a faun  costume and we wanted some white spots on it.
I recall Matrices having a tutorial for making pretty spots using some yarn and a large needle but I have been unsucessful in finding it. i believe it was for her Binturong character. Could anyone help us out?

Edit: Well i found the link, but it missing most of the photos showing some much needed parts :<
