I made matching hearts for me and my boyfriend :)
I made the 'Jim' one first and when I finished it he said "aww hunny thankyou that's lovely!" and I was like "err actually it's not for you, it's for me to wear and show everyone that I love you! But I'll make you one too :)" Thus the 'Britta' badge was born!
I stuffed them with tiny left-over scraps of felt and they attach at the back with a safety-pin.
