Facebook pages are always good, I know it's pretty obvious but I've gained lots of people through posting on my page. And you can promote Facebook posts too to reach a bigger audience. Facebook is also really good to advertise offers & discounts. Also, posting on facebook selling pages about your business helps loads, post offers on facebook selling pages for your area and bridal pages are also amazing as there are always people looking for things for weddings, just put in a request to join the pages and you can then post photos of your work in them. I hope this helped x
