While searching for unique social activities for a club of which I am a member, I ran across many fundraising ideas. Some of these seemed worthwhile either for social activities and/or fundraising. You may judge and contribute your own activites and fundraisers.
Examples from the message board site below. Also search for fundraising online.
"Quiz nights, 'themed' suppers (curry nights, St. Patrick's, Harvest supper, etc.,), treasure hunt, Bonfire night party, talks on local interest, choir and poetry recitals, monthly cooked breakfast, sponsored ramble.
Tutored wine tasting, casino night, cookery demo, BBQ, barn dance, fashion show, talent competition, walk, street party, beer festival, treasure hunt, local food fair."
