I’ll admit I’m pretty self-conscious about drawing in public, and this coupled with a natural penchant for neatness (read ‘obsessive’) I try to find the most compact set of utensils. So rather than spending even more more money, I came up with this solution: the tin measures 7.5 cm by 4 cm (or 3 ins. x 1.5 ins) with five pans from a Daler Rowney set. So I think that with a water-brush I’ll be ready to take on the world, or at least surreptitiously sketch a small part of it!!
