Washougalwonder posted some nice pics of what look to be fully developed buds.

Personally I had a similar question to yours in WHERE do these, and HOW do these form. I've seen plenty of finished bud in my life and torn it apart MANY times. However it's likely the first thing I ever took apart and didn't notice HOW it was put together in the first place.

So I've got some pics of my colas I took just over a week ago. Although it's hard to get the camera to focus on the correct spot, so the focal point may be a bud leaf tip or a hair.
