I was prompted to start this thread after seeing the following video by Kevin MacLeod (the Down to Earth Woodworker one).

A butterfly key or bow tie stitch is a good way of turning a crack in a bowl into a feature.

I haven't done any in quite a while, but here is an example from some time ago.

Kevin covers the basics. The only difference from flat work is that we are working on a curved surface and are also likely to see the key on both the inside and outside of the bowl, in which case undercutting the keyway as suggested in the video doesn't work.

Tip: If you make the key a lose fit and set with a contrasting coloured glue, you add an additional decorative element and the fitting isn't so exacting.

Neil, the Hawaiians have been using pewas for centuries to repair traditional calabash bowls. I think you can even purchase a router jig & kit for making them through one of the Hawiian clubs or turners.

Kelly Dunn uses them extensively http://www.kellydunnwoodturner.com/ & http://www.kellydunnwoodturner.com/index.php?option=com_content&view=article&id=119&Itemid=134

Yes, Moby, the Hawaiians not only used them out of necessity to 'save' their calabash bowls, but have also perfected their use, IMO.

A few more examples... here (http://kawikahuliwood.com/2011/10/08/the-elusive-calabash-form/) and an old one here (http://www.1stdibs.com/furniture/dining-entertaining/bowls/museum-quality-18th-c-hawaiian-kou-wood-calabash/id-f_759066/#).
