You got the idea. I have a funnel with a screen and did the same thing to get the leaves out. I used a cup to skim off the extra water. After it settled, I ran the hash water through the coffee filter and let it drain. I layed the filter flat on the counter. Then I took a plastic card and scraped the paste onto a piece of dry cardboard. I sped up the drying by placing it on a warm surface. I pinched the dry powder between my fingers and it made a nice little chunk of hash. I'm going to look for some nylon or steel mesh and make a better set-up.
