I spent last weekend at GreatArt in Shoreditch, London as artist in residence, drawing and painting on the Saturday and running workshops on the Sunday. For a change I was working from the theme of flowers and plants.
This flagship art store is THE place to go for reasonably priced materials – I always use their Gerstaeker deep-edge canvases. https://www.greatart.co.uk/london-shoreditch.html
