Having bowl blanks is a recourse I have tapped into for years when Richard Raffan used to bring bags of his offcuts to the club and dispose of them at a price, yours are unusual in that you can select those that have suitable grain for pens as well. Three very economic pens at that because one piece pens are frugal in fact three pens can be made from each of my recent blanks,thus profit v cost zooms.
Stained interest like stained glass enables great to emerge from ordinary you have proved that then your two "normal" are special blanks also. Neil three good examples mate.
