Having an odd piece of vilene, I decided to test it with brusho and this is the result.
As you can see from the right one, I tried to stamp with bleach but nothing really happened, so I decided to go with a couple of solid stamps but detailed ones still stamped well on it too.
Right is the vilene with an iron on lining and left is the result of pressing on top after the brusho has been added.
Again the ink really sunk into the material (now switched to the left side) and right, hexagons stamped in bleach to remove the colour.
