Decide on a photo, size and medium you want your portrait to be. The most popular size is 30X40cm but if you want something more affordable, you can choose a smaller portrait size, like 20X30cm. You could also find a frame you like first and order a portrait to fit the frame. I often use Profile Frames which are a very good make. They can be ordered on profileproducts.com.au. Your photo should be one that is in daylight or clear light as coloured light will change the colour of you animal friend. I usually draw with soft pastel which but i can do black and white, which is graphite or charcoal.
