Muslim Homeschool Network
Open to mothers in Orange, LA, Riverside, San Bernardino, and San Diego counties. They host workshop and field trips and other activities as well as provide support to Muslim homeschoolers in SoCal.
Fees are currently $20 per year per family. The fee help "provide numerous services at a low cost to the Muslim homeschool community in the areas of social, educational, Islamic, leadership, and support and outreach, and help fund scholarships for less fortunate Muslim homeschooling families."
I have corresponded with a sister from this network and I'd love to be a part of it but I'm a little far from the venues where the events are held.
They also have an email list that you can subscribe to.
