Seems like they should make fraying worst but that is not the
case in my limited experimental evidence

The reason they work is that they make bias cuts, which do not ravel.

Try this: Take a piece of woven cotton fabric, and cut it on the bias, or at a 45 degree angle (which is the true bias of fabric). Then try to make it fray. You'll see why the constant /\/\/\/\/\/\ of pinking keeps the fabric from fraying.

Be careful though! Tight weaves are fine with pinking, but on loose weaves like tweed and silk dupion, they INCREASE the fraying exponentially! ;) Can you say 'My fabric is evaporating?'


Good point, Kate. But then dupioni frays, no matter what you do, especially if you prewash it! The only way to keep it from happening is to overlock or overcast the edge. Some poly satins do this, too.

And a few other fabrics I've discovered, like organza and slipper satin...

I'm not talking to you, Kate, as I know you already know this. I'm speaking to the OP, just bouncing off your post.
