Is anyone good at making new hashes?

I've got half a gram of hash that's 40% THC and a couple grams of hash that's 80% THC. The idea is to combine the two and roll them together to make a big batch of hash that's just generally better than the first. <br><br>I've got some fish oil to help out with the rolling but I have no idea where to start. Any tips or help would be greatly appreciated!
