All of my paper based mediums such as graphite, colour pencil and pastel portraits are sent mounted. I mount all portraits myself and have two colour options – soft white and black. These mounts are made to fit standard size frames. An A4 portrait would be mounted to fit a 12″ x 16 frame and a A3 portrait would be mounted to fit a 16″ x 20″ frame. If the client is planning on having the artwork professionally framed I can either post the portrait unmounted so that the client and framer can pick their preference.
My normal procedure when completing a portrait is to take photographs of both options for my client to pick their favourite. The soft white works with all portraits but in some cases the black really enhances the artwork.
I am very fortunate to have a local framer who has a huge range of mount options. So if a portrait required something more or potentially a double mount I can take the portrait to him, photograph the options that compliment the portrait best for the client to pick their favourite.
