I want to start making my own muletape tack, but there is limited articles I can find on how. I did find a decent video on how to, but they don't specify how many feet of meuletape you need, how thick, or anything. Does anybody have any tips/websites/videos you recommend? I saw the braids by Brette's academy, but it's kind of expensive for me right now, especially with it being close to the holidays. TIA. :)

I don't think what your looking for exists in the form of a "how to" document.  Because the people who custom make good quality tack have put in the blood sweat tears and investment to figure it out and guard their craft closely.
