I've now added a selection of greetings cards to the Mighty Fine Art website. I'm selling these as a set of 8 and hope to get more sets available sometime soon.
I'm glad I made the effort though. They sold well and the fact that they have my website details on the back is great for a bit of self-promotion. Incidentally, I used the company called Centreprint to get them and I'm very pleased with the product quality and service received.
As I'm doing so many craft fairs and small events now, these will be my 'bread and butter' money when other sales are slow, hopefully enabling me to at least break even on the day.
