I've become a huge fan of Etsy; it's a fabulous website if you are looking for handcrafted and handmade items,vintage goods or craft suplies. It is the most fantastic place for finding unusual gifts for others or yourself- escaping the mass produced and supporting individual crafters and designers. There are sellers from all over the world and lots of british sellers - to find them add 'british' to your search when looking for items.
