Hash Making? Hash Bags?

I've been doing a lot of research on hash making and I'm wonder about these hash bags/bubble bags. I was wondering if anyone has come across a pattern to make your own hash bags....
Also does anyone one know of a place i could get the screens really cheap?

Have you looked into the Gumby method of making hash? No bags required. Google it, there are some great youtube videos on it.

i always rock the gumby methode but it wont get you the diffrnt grades it will all be the same just plain ol good hash! look it up on youtube
