Resources
These are resources I've found and used. If you are a bookbinder yourself or are simply curious, here are my top recommendations!
YOUTUBERS
Here are my favorite bookbinding youtubers who have both inspired and taught me so much.
This was the first youtuber I ever watched regarding bookbinding. Her binding techniques and tutorials are very helpful and easy to follow.
Chanel was the second bookbinder I found on Youtube. Her projects are so clean and elegant, she has lots of helpful info on tools and materials, and just came out with a wonderful book (Handmade Books at Home) full of projects from beginner to advanced. I used the info in this book when making my Shakespeare book.
DAS Bookbinding is an experienced bookbinder on Youtube with many tutorials as well. If you are looking to try more advanced methods, this is a great one.
Four Keys Book Arts has full length videos documenting the process he uses to make incredible books. He makes a lot of medieval inspired leather bound books. and has some great tutorials.
Ingenious Designs is a wonderful resource for anyone looking to make stunning books on a budget. From sourcing affordable leather to cheaper methods of edge gilding, his videos are a great resource.
Nik has a lot of great projects, simple tutorials, advanced tutorials, and various bookbinding content. For getting a better feel for how paper marbling is done, to making crazy book covers with a laser engraver, her channel is awesome.
MATERIALS
I personally use Hollander's more than Talas due to their wider range of decorative paper, but both are great resources.
