My name RockePloeger and I have been making friendship bracelets for approximately fifteen years now. Where as I used to do them for friends, I am now selling them on etsy (you can find a link to my store at the bottom of the page).
I can to a wide range of bracelets on the site, including your three main types (normal, alpha and kumihimo). I am trying to create a set of tutorials that will be available for everyone, both on this site and youtube. If you have any suggestions for future tutorials then by all means send me a message and I will do my best to full-fill your request.
You may also notice that I am a moderator on this site. I take my job very seriously, and will do what I have to in order to keep the site running smoothly. If you have any questions, feel free to send me a PM. If I cannot answer the question myself, I will do what I can in order to find the answer for you.
Below are some links that could be of help:
