Plaster of Paris botanical plaque

It so happened that I was booked on a workshop to learn about the creation of plaster of Paris wall plaques using botanical material.  It so happens that I have Dad's funeral flowers at home so I took some with me to the workshop to have a go at creating an artistic botanical image.  It now needs cleaning carefully with a small brush everyday this week to remove as much of the original clay as possible.  I would try and spread individual pieces out a little more  if I had another go.  I really enjoyed doing this and I have something concrete(!) to look at.
