Firstly, I really wish that Paperchase would sort out their website. It doesn't seem to catch up to what they have in store very quickly and the variety of their goods available to buy on-line, via Amazon, is shocking. They're one of my favourite shops, and I've found some great cupcake goodies there but they need to sort out their on-line presence imo.
They have a few gifts instore for cupcake lovers this Valentines day, including this rather nice notebook which I very nearly bought but I have about 10 cupcake notebooks lying empty and I just cannot justify buying anymore! They also have this cute birthday and anniversary book - which is a bit too organised for me, and hardly anyone I know gets married so the anniversary part would be a waste, but I'm sure some people would find it immensely useful.
Finally, they also have a choice of cupcake valentines cards - my favourite one says "you're my cupcake" (available in the Covent Garden store if anyone is interested..ahem!) but that one isn't available online but this "I think you're yummy" one is rather cute too. Oh and its not cupcake related but for all you Twitter fans out there this "You're so tweet" card is just perfect!
My advice with Paperchase, if you're near one go instore for a much better selection of cupcake and Valentine goodies. They have the red heart shaped kitchenware again, including bowls, measuring spoons and egg cups - I love the giant bowl I got last year!
