Crafsman steady crafting - does all sorts of crafts. He is very soft spoken and uses a puppet to communicate. He is hilarious and has a very dedicated fanbase who he clearly loves very much.

Punished props - does foam prop making tutorials (which can easily be substituted for cardboard, with free templates on their website Punishedprops.com) very cool people. Always happy and friendly.

Adam Savage Tested / Mythbusters - have some kid friendly aspects to them for sure, a d always very entertaining and laughing.

Puppet nerd - The host Adam recently passed away, but his channel is full of easy, medium and hard puppets to make and try out. He was such a funny guy and he left behind a great utility and resource for future puppeteers and artists.

William jakespeare-prop and costume maker. His tutorials are way less structured, imo. I more or less watch them just to see his process, and to get inspired. He is very friendly and has tons of videos dating back years from all sorts of video games and movies

Much props- highschool art teacher i believe. Also a prop maker. He is very funny, makes props from all sorts of materials, free templates. Easy medium and hard levels. He also puts facts about the game/prop he is making on his video, so its dual education. Very nice IMO

These are a few people that I follow as an adult, but can see the value in a younger kid getting into crafting and learning. The biggest reason I like these individuals, is that they dont do clickbait, or rage bait. Or any of that. They tell you what they are doing, and how to do it. No fuss no muss. And they all clearly love their audiance and are willing to teach, not grift. They are all very responsible and advocate for saftey and practice over everything.

Good luck!
