If your gonna cut them up to dry them there is no specific way to chop them up.
Your going to want to remove all the fan leaves first (all the big leaves with a single stem) Then you can just cut them up into manageable sections, dont take too much because you dont want to lay buds down on a table.
Start with a lower branch, cut it off, then cut it into sections short enough to hang. You can leave a little branch sticking out to hang them.
Theres to one way, just do one bit at a time, dont go for too much, and when you hang it to dry make sure buds are separated and not touching so air can flow through easily.
