I've been collecting internet things for awhile.
I've got 2 or 3 books on braiding - but honestly my head wasn't prepared for changing the way I think enough to use them. Example, worked on turkshead knots off Grant's book & couldn't get it - so found a pdf set on here (dead link & missing first file). Since the beginning was missing it took my another 3 months to go back & another month after that before I progressed at all.
I pick the brains of the guys at tandysleather in Bloomington, MN for stuff & then internet.
There's a local MN leather guild (http://www.leatherguild.org/) chaired by Johan Potgieter of South Africa and Ron another excellet cowboy leather worker. ( http://www.johan-potgieter.com).
I'm an every three months type of leather worker, will spend a week or two figuring out a new design. I kicked off a blog where I could record the online stuff - lately I go here in these orders:
etsy.com to help me see what is out there from other people & see if there's better ways than what I have in mind
pinterest.com has tons of resources taken from books
instructables.com .. I adapt their normal clothing or whip instructions to make my own stuff ... sometimes you have to dig some
youtube.com, but it's not as good as instructables for me, though it's a great supplement to the ground work laid on instructables
here ... I normally compare what is on instructables to a search of this website for differences on leather versus other types of material
One of the things I really miss out on is advice like - which progression of skills to acquire for ease of learning, the substitute for expensive tools is always hand skill & tricks for "perfect" or less imperfect cuts. Example: I started cutting leather on my floor for smoother edges & setting up a full workshop isn't an option.
