I take it branch by branch, first removing the bigger leaves, then trimming the sugar leaves, then hanging. But, some prefer to trim dry. If it's your first harvest, perhaps try some wet-trimmed and some dry-trimmed, and see which you like more.
Either way, you'll also need some good music, a comfortable chair, and something to smoke on while trimming. Of course, make sure to save your tiny popcorn buds and sugar leaves for hash. Otherwise, just enjoy it!
Cheers!
