Sorry Dazzler. this topic must have got pushed down before I saw it last time you posted. I think it is GREAT and 12 members will be plenty for your first run through... enough for lots of fun (and a little friendly competition between them), but few enough to keep track of easily! Encourage your kids to ake part in the other aspects in the club if possible, like speech competitions and whatnot, the 4H program gives the most benefits to the kids who use the whole organization rather than just tapping the resources of their project leaders, who still mean the world to some kids, especially those that come from rough homes, or love the project bu can't afford to take it up on their own (as is often the case with livestock projects).
I think your involvement with this is great and its something I hope to do, and for my future children to do in later years. 4H is good cause there is something for everyone, and always room to expand to new horizons. My how the organization has changed and grown, thanks to leaders and volunteers like yourself!
