Detail of one of my icons of St. Mary Magdalene.  This icon was purchased to be presented as an ordination gift to a Methodist minister.

 I'm laying out the drawing of the icon of Pentecost.  To get the scale of the figures right for the icon board I placed a sheet of white paper on the board, then I drew directly on the vellum with pencil, then I traced over the pencil with India ink.  After that I put a carbon under the vellum, removed the white paper, and traced the drawing directly onto the gesso of the board.  It's a bit round-about, but since the drawing is ca. 24 inches long and 14 inches high, the icon board was the best surface I had to work on!
