Thanks Karen and thanks to everyone who responded.
I did not know that about the bias cut but that makes sense to
me.
So does that mean one does *not* use pinking sheers on the true
bias ?
because the pinking bias-izer would be countered by the true bias
making lots of little pinked / cross grain cuts ?
thanks again,
