basically you cut off the front and back crotch points along the grain (usually a straight line up from just above the knee, parralel to the longwise grain) Then combine the two pieces (one front, one back) along what would be the inseam seam, and draw a straight line across the wide part. You should now have a triangle. The straight line will be the edge of your gusset pattern that is "place on fold". This give you the diamond shaped piece when you cut it out. Be sure you know which long edge of the diamond go on the front or back of the pants leg. The two "corners" of the edge of the fold ( short points of the diamond) will be where you match up to CF and CB when you insert the gusset.
Hope that's more clear than mud.
