Are you a member of Anglian Potters? They are really good and supportive with events and exhibitions in your area which you could take part in alongside your Folksy presence. Speaking from a financial and personal point of view I find the Folksy Basic account suits my needs better than Plus, particularly as I am not a social media user and most of the Plus promotional activity is geared to that. I too think your work is lovely - do keep going!
I tried to start a showcase thread to support fellow ceramics makers on here, but there was little interest I’m afraid, and I didn’t want to flood it with my own work. You’re welcome to post images there if you would like to!
PS Just bought one of your bags…
