how to make hash?

I was just wondering how, I bought cervantes' grow book and he states to save the leaves from trimming the buds, I was just wondering how to prepare into goopey hash. I youtube searched and a variety of things arose, but there was quite a variety of preperations, which is best? Also I don't have a youtube account and don't want to make one, and the youtube won't let me view....

This ain't my vid, but it is how I make hash. I hope it worked.

If you want there are a ton of ways to do it. That way ^ is just my preferred way. If you want you can make bubble hash. Most say this is the BEST way. Gumby hash is another good way, but it takes 4ever. Dry sieving is labor intensive, but WAY worth it. Same with hand rubbing. There is also the hash oil route. BHO, and ISO hash are all great ways to get ALOT of hash cheaply, but it is dangerous. Just pick the way you want to , and go for it. If it doesn't work out, try again til you get it right.
Good luck and happy smoking!
