Hey Janice! Inviting friends is a great way but while you’re here, follow anyone you like! They should follow you back too. I can make some recommendations to help match you with some locals :-)
My suggestion would be to click on the profile of someone in your area and then look at who they are following and follow them. Most of the time they will follow you back. Also, invite some friends you know who would enjoy Fresh Chalk so they can follow you and so on and so on 😀
