A couple of good sources for that would be…
Star Wars Costumes: The Original Trilogy book - https://starwars.fandom.com/wiki/Star_Wars_Costumes:_The_Original_Trilogy
The Making of Return of the Jedi book - https://starwars.fandom.com/wiki/The_Making_of_Return_of_the_Jedi
This may also give you an idea of it…
Behind the Scenes - Warwick and Son - Star Wars Episode IX The Rise of Skywalker 2019 - 5 minute youtube video
Return of the Ewok - 25 minute video
Probably some of the ‘Making Of’ videos for the 2 mid-80s Ewok theatrical films?
And fan-made tribute videos to the likes of Stuart Freeborn and other costume contributors?
www.tomspinadesigns.com/restoration/star-wars-props/return-of-the-jedi-ewok-masks-displays - from TS is pretty cool.

That’s all I got and can think of right now…
Good luck with it. 👍
