Hessian can be used to make shaggy rag rugs by using a rag rugger tool and rags cut up out of clothes.
Hessian [per 1 metre cut from 1 metre wide roll]
The secret of rag rug making on hessian is to make the weave, of the hessian, as tight as you can. The way to do that is to keep the pieces of cloth close together so put the second short strip in, using exactly the same technique, two to four strands away from the first. It doesn't matter which direction you go in and you still don't need to be precise. It's not a good idea to put two pieces of cloth into the same hole, in the backcloth, simply because this means more slippery materials will slide against each other and may come out - as long as each hole only has one piece of cloth in it you can make a rug from virtually any material, including carrier bags.
