Hi, I am organising a fundraising event in September and all funds will go to the stroke association and NICU. My father has had a series if strokes over the years and my daughter was born in 2012 with the unexpected life long complications and spent her first 10 weeks at southmead NICU. As both charities are very close to my heart I am planning a sale and fun day. Is £20 too much to charge stall holders? I keep being given conflicting advice so if you can advise that would help. I will be requesting stall holders make a raffle contribution too. Thanks
