Knotting
Each rug is made up of a series of knots running horizontally along the warp, these are visible on the rug's reverse side.
Fringe
The fringe is the exposed area of the 'warp strings'. These strings run through the entire length of the rug.
Selvedge
This is the bound edge along the width of the rug. The selvedge prevents materials from fraying or unravelling.
