Darning Loom
Such a practical little device! Also known as a Speedweave Loom
This simple loom allows you to mend all sorts of holes and tears, not just in knitwear - it will mend holes in jeans and other fabrics too.
The loom consists of a wooden disk that fits behind the area being repaired. The loom section is secured to the disk with a sturdy rubberband (included) and the extra large darning needle and hook tool make weaving your repair so simple.
