This knicker weight fabric has a finished useable selvedge top and bottom). This means that you actually utilise the selvedge at the top (waistband) of your knickers, so you can use a fine slim elastic and simply sandwich that in the seam without causing bulk. this is the sort of fabric now being used to create a very discrete knicker that doesn't show through tight clothing.
This also makes a great powernet substitute for smaller sizes, or use below a lace or other stretch fabric to give sufficient strength for the bra wing in larger sizes.
Powernet is a mesh type fabric, which comes in different weights. The heavier the weight the stronger the stretch. This section is of light powernet which is most suited to making knickers etc. We have indicated stretch as W-widthways stretch, selvedge to sevedge, and H-stretch down the length of the fabric. These are approximate. A 50% stretch means 10cm of fabric would stretch to 15cm long, and 100% stretch means 10cm of fabric would stretch to 20cm long etc.
