John Scheid miniatures and Grenadier caps

[B6BosGO]

 I am hoping someone here can give me some information.  John Scheid was a miniature figure and diorama maker in North America in the late 1950's and early 1960's.  He created a marvelous diorama of the fight on Lexington green 19 April 1775.  The figures are all 54mm. 

Of especially interesting is his method if doing Grenadier/Fusilier caps.  They actually look like fur.  But how did he do this?

If anyone knows anything about him, his figures is his methods I was his be most in interested.  Thank you!

If I were to make an educated guess, I would think he used a rough shape in plastic or even the base model's headpiece and then covered it in fine model gras in order to create the fur effect. Then probably spray painted it.

Could also be some type of sponge or pipe cleaner perhaps.
