I've made a whole new page on this wee site of mine for selling greetings cards with the sole aim of supporting charities.
Currently, I've only set up an arrangement with one - The Freedom Project, which helps to rescue women and children from abuse and a life of trafficking. They restore them in every sense of the word (often involving surgery), and place them in an environment where they are valued and loved.
So have a browse, receive something beautiful in the post, and know that someone somewhere is grateful.
If you are a charity and would like to collaborate, I would love to hear from you. Please use the contact form to get in touch!
