@szaaaaa if you understand how to tie one alpha, you understand how to tie any alpha. I recommend checking out MashaKnots' tutorial on the flat alpha technique. As your first alpha I would recommend one with less colours.
@kamilii777 Sorry for the late reply! You should watch MashaKnots' YouTube video on the flat alpha technique. Once you know how to do that, you can make any alpha! Her account on here is @Racoon, and #19454 just has her alpha tutorial on it. I hope this helps!!
