Every Month Fundraising

So, there's this great charity based in Manchester called Every Month (extending to South London soon) and they make sure that menstrual products are available for everyone. They make these packs up and give them out and I love their hands on approach to tackling period poverty, something we should not have in this day and age.
So, they're running  a campaign to get people - like me- to raise £100 in 100 days.
I don't know what I'm going to do yet - clean your windows? I haven't thought it through... but I will smash this target with your help.
