I just recently purchased this set of stationary in a Hood River stationary store. I love Cath Kidston's designs! She is a London designer who's style has this wonderful retro look to it. I first saw it in a little shop at the coast where they had some of her products: Ironing board covers, oil cloth tablecloths and aprons - I fell in love with them.
I have looked for her fabrics everywhere but apparently, they are only for sale in the UK. You can order them online from her website, however. Well, now that I have this pretty stationary, perhaps I should write a letter!
