Go online and sign up to Baker Ross - they've got TONS of stuff! Also, part of the same company, is Yellow Moon which is a fund-raising version of the same. They'll send you a minimum of 20 catalogues to hand out to parents, with a percentage of any orders made using your youth club's code coming back to you in a cheque.
You'll be swamped with ideas, and I can promise you'll have kids itching to join in!!!
They've been fantastic for craft sessions at two play groups I helped to run and I can't praise them highly enough...
