I spent a lot of time in the British Museum whilst studying for my Degree. My work has changed considerably since then but it is still a place I return to again and again. Inspiration doesn't always come from objects in the collection but also from the space and its visitors.
There are many quirky book stores in London, but I really love the selection that Daunt Books have, they often have bespoke editions which you won't find in other book stores. Also, the people that work there are so helpful and knowledgable. I can never stop myself from walking in!
A great walk down an old abandoned rail way from Finsbury Park to Highgate. Most of the original platforms are sill remaining so its an interesting place to explore...
Cordings situated in piccadilly is a renowned establishment for British Country clothing and tailoring - that can not only kit you out to shoot pheasant in the finest yellow ochre cords but for me offers a great selection of socks.
