Digital BW, The Print

I just read the post from Mr.Roark, in which he states "I use 1/2 inch 
cloth bias tape now instead of a strip of folded paper towel
to get to the underside of the head". I immediately said to 
myself, "self, what on earth is cloth bias tape?"

So I looked it up (google), and now I am prepared to share this 
critical information to the DigitalBlackandWhiteThePrint forum:

Quoted from textilefiberspace.com:  "Bias tape is made from a strip of 
fabric that has been cut along the bias grain of the fabric and folded 
in one of two ways. There are two main types of bias tape - single fold 
and double fold."

The next question of course, what is bias grain? I tried to learn that 
too, but quickly decided it was of interest only to textile freaks, and 
not important to the subject of printing. Anyway, I would assume that 
one could purchase cloth bias tape from any fabric store or from your 
typical 'department' store.
