I normally paint on Hahnemuhle or Canson Heritage paper that is 24x30 or 23x31. I normally tend to choose this paper if the illustration is going to be framed because I found that it is difficult to find off-the-shelf frames of those dimensions. If you order illustration only, I tend to paint in Arches A4 as it is much easier to find frames for.
Either way, I will discuss with you before I commence the work just to make sure that you are happy with the final size.

99% of my paints are Daniel Smith and tend to choose, as much as possible, colours with excellent lightfastness.
The rest are Winsor & Newton Professional and White Nights.

The actual frame is made of Tulip Wood, the glass is acrylic and the backing board is paper-base.

I choose to paint the frames in Black as it always complements the artwork and works with everything.

If would you like a different colour, just drop me a message.
