 Honeycomb is fine but for small pieces like these ribs where you need to
 clean out the honeycomb between the thin glass … it gets a little tedius. I
 made my ribs of foam and am glad of it. Easier to work with the smaller
 pieces.
 
 Don’t recall having a problem matching the rib curves with the skins.
