Bone keys

[Ellsworth]

I would add to what Stephen Birkett says about bone, that sun-bleaching it
works extremely well.  Set the pieces out on a tray in the sun, with the side
upward you will put on top, and repeat for several days.  Keep one inside to
compare.  It will get very white, esp with strong sun.  I've had it work fine
even iin winter in Wisconsin.
