Paper cloth is a great technique for using up all those pieces of paper ephemera!
The papers are layered up with muslin and tissue to make paper cloth sheets which are really robust and can be cut, stitched and glued. I use these paper cloth sheets to make books covers for my handmade books as well as using them in collage and small 3D pieces, such as jewellery and baskets.
