Cass Art
58–62 Heath Street Hampstead London NW3 1EN
Cass Art is a terrific five-store chain of art supplies shops, and the Hampstead location is a well-stocked branch, good for paints, brushes, pencils and papers, through to easels and mannequins, all competitively-priced. There’s a fine selection of craft-related materials, too, and plenty of gift possibilities for kids.
