I have used a lot of tools and materials in my time, so I've made a list of my favorite things and where to find them. Hope this will help you find what you're looking for! Amazon links are affiliate.
Clay and Sculpting
The Monster Makers Clay - Hands down my favorite sculpting clay. It's an oil wax hybrid clay, you can melt it down to a liquid and pour it into molds, but when cool it can be carved more like wax. It doesn't leave near as much residue on hands and surfaces that oil clays leave. I use medium hardness for everything
Stainless Steel Wax carving dental tools - very effective tools, I do most my sculpting with these
Scaled Sculpting Armatures - Shamless plug for my own shop, but the reason I sell these is because they are invaluable tools in my process. I use these all the time for idea or even taking a pattern from.
Drawing and Planning
Confidant Hardcover Notebook by Baronfig - (I like the plus size) is my absolute favorite sketchbook I've ever had. nice smooth paper, a sturdy cover, and the pages open and stay flat. Get $10 off using this link.

Neewer CM28 Wireless Lavalier Mic - I have been so happy with the quality and ease of use of these lav mics. The freedom of movement with the wireless has been amazing after upgrading to a wired one
NEEWER ST3 C Clamp Webcam Stand Camera Mount - This has been a huge upgrade and has helped me eliminate so much stress with mounting my camera. the arm is strong and holds steady and I can get the camera exactly where I want it without worrying about it falling over.
K&F concept tripod - Again, a solid tripod to mount my camera on and not worry about it falling over. I love the build quality and it packs down quite small.

Wefting and Latch Hooking
Kanekalon Jumbo Braiding hair -Huge variety of colors and a great texture. The heat level is perfect for my latch hooking technique as the fibers in the knot can be melted together for a very secure attachment.
