Tearaway backing made from cotton fibres produced and interesting background to try.
In fact I have meshed same to same by tearing pieces from another sheet. The background is coloured with a dilute solution of walnut ink mixed with a few drops of red food colouring. The applied shapes came from a sheet coloured with procion dyes
This is the back of the finished sample. You can see the areas where most meshing has taken place. Too much work will produce holes, but that can be an interesting feature too.
