At the weekend I popped into Paperchase and happened to spot these cupcake goodies.
They have a few more cute bits but they didn't have them in the store I went to, however if you're interested your best bet is probably to go to the giant store in Tottenham Court Road or the Westfield one as they tend to have everything!
The bottom pic is a roll of wrapping paper - I have a wild idea that I will wallpaper one of my kitchen walls in this and then varnish over it or something - I wonder if that's possible..time for me to do some Google research!
