I know the name is misleading.... but don't press the wet hash in the pressing screen. Instead, lets call it the dabbing screen. Put the wet hash goo blob from the bag on the dabbing screen, gently fold the dabbing screen over the wet hash blob, gently enclose the folded blob in some folded up paper towel and just let the water wick out thru the dabbing screen, and keep moving the paper towel(s) around untill most of the moisture is wicked out. Then take the still wet blob of hash off the dabbing screen, not much should have stuck to it as next to no pressure was used (right?), and the big wet blob should pick up stray bits easily just by plopping it on them gently. Then take yer hash blob to the cardboard, and while still wet, use a knife or somesuch to 'chop' up the blob. It should kind of be like chopping up wet sand if you've left enough moisture in it. Chop as fine as you can and spread it out on the cardboard. Over a few days the air will dry your hash powder some (put it in a safe spot), but the cardboard will actually wick out most of the moisture. The powdered hash is easier to deal with and smoke in the end anyway, and pressing bruises the precious collection. If you must press it, wait untill the powder is fully dry, then press that. Some grades of some strains will still be sticky chopping it up, but the trick is leaving enuff water in the patties to get them to chop up. Hope this helps some.
