My initial thoughts were to do a monthly newsletter that sums the month up, gives you an update of what I am working on, when it will be available, advance sales on said items (so before they are published on Folksy or Facebook). I thought I would also include incentives and discounts, and news of sales that I am running. I could also include a detailed list of which events I am attending etc.
If you are interested in joining up, use the contact form tab above and write Newsletter in the subject line and I will add you to the subscriber list. As an incentive there will be a discount code in the first newsletter that will be exclusive to subscribers.
