LOL I knew you were gonna say you are home schooled! The school might let you take the class anyway, it's worth a phone call, with your parents blessing of course. I know our school lets home schoolers come in for some classes, usually the electives like art, band, choir, and PE too. Like I said it may be something you can ask your parents to check into.
The 4H idea is a good one as well as the church. You may also want to look up your nearest quilt guild, I'm sure they'd love to have you.
