The implied answer seems to be that hybrids are made more or less the same way as conformers.

Based on my own experiment earlier today it appears that dynamic parts need to be rigged (i.e. attached to a bone), otherwise they don't show up in the list of parts to be clothified.

Also, conforming clothing is generally modeled using neatly arranged quads used sparingly, whereas dynamics tend to benefit from an evenly distibuted and dense mesh (delauney triangulation). The threads about dynamic clothing linked to in the stickied post in this forum provide more detail.

I suppose the mini-tutorial then would be:

1. Create your item as if it were a conformer, but follow the guidelines for modeling dynamic cloth for the parts that are to be clothified.

2. Rig the mesh like any conformer.

That said, I'm sure there's more to this. Please correct any mistakes and add more details about best practices, et cetera. :)
