The US seem to have a much better selection. I like the fabric sash stands from raisethecake.com which are custom designed to match your wedding cake colour scheme. If you are looking for a vintage feel therochestudio.com has a nice selection of vintage cake stands for sale in a varity of styles and designs from large wedding cake platters to small single cupcake stands. And look at the cute wraught iron cupcake trees by bosscupcakestands.com! I want one!
Luckily they all ship to the UK!
