Things to do with non-skid rubberized shelf liner

 This great material is made by a number of companies and can be found at your hardware store or department store, pharmacy or grocery store. It also comes in different thicknesses. 
Sewing: Leave a square by your machine so that your scissors,  your seam ripper, or other little sewing notions that want to fall on the floor stay put when you toss them down.
Machine Quilting: cut little squares and place under your fingers to help grip material during free motion quilting;
Serging: Cut a thicker (or double) square the size of your "serger footprint" to keep it from "walking" when serging at high speeds;
Hooped Embroidery: 
When working with thin fabrics, using lightweight shelf  liner, cut strips 1" by 4" to 6" or more (depending on the size of your hoop) and tuck into the long sides of your hoop so that it grips your fabric more tightly. The liner lies on top of your fabric between the top fabric and the inner hoop.
using lightweight liner, cut a small square and use it to grip the tightening screw on the hoop if you have a touch of arthritis or lack hand strength
