 soft deal board, about one foot and a half long by one foot 

 wide, with a narrow bead tacked round the edge so as to 

 convert it into a shallow tray : the advantages of this are 

 that the subject may be turned in any direction without 

 unfastening, and that the edge confines the mess caused by
