Whilst out walking a couple of months ago I saw these rose hips on a bush by the side of the path and picked a couple of stems. I always keep a supply of easy seal plastic bags with me so that the flowers I pick stay fresh until I get home and put them in water.
I used Winsor and Newton Alizarin Crimson for the berries and SAA Sap Green mixed with a little Ultramarine Blue for the leaves and stem.
The SAA, or Society for all Artists has a fantastic on-line shop, with huge discounts for members. Membership is very reasonable and includes Paint magazine, full of useful advice and step-by-step painting projects.
