Fabric Chenille Brush
 
Londa says:  "This is hands-down, the BEST stiff brush for creating 'fringed' edges on bias cut fabric.  I have a limited stock, and my supplier isn't sure they will be making the HUGE commitment to order additional stock once these are gone, so add it to your creative sewing tools NOW!  This is SEW much better than a stiff toothbrush, and a wire brush from the hardware store is too stiff.  Believe me, I've tried!.  All of the fringed trim seen on my Creative Sweatshirt Jackets in the Inspiration Gallery have been created with layered (at least 2 - up to 4 layers) of 3/4" wide bias strips 'roughed up' with this brush."
