I ALWAYS wanted a Spirograph when I was little. My cousin had one that she used to let me use sometimes. I loved drawing the swirly whirly patterns with red, green, blue & black ballpoint pens – often carefully colouring them in afterwards.

This vintage Denys Fisher set is for sale in support of OXFAM GB*

*Oxfam. What springs to mind? Charity shops and second-hand clothes? Africa? Think bigger. Much bigger. Last year, our emergency and development work reached a staggering 15 million people in 94 countries! Thanks to people like you.
