This are the outcome of cutting and tearing the plate and using gel medium
and this using a plaster/PVA/water mixture. I am trying to get the effect of the tide line on the beach (hopefully making the most basic mistake of cutting the text the wrong way round on the sample will mean I don't do it on the final block).
This is made by using different tapes and by cutting into the board. It is for a book about museum collections.
