The Accuquilt and Beyond Facebook group members post all the time about their custom dies. The cost depends on the size and how intricate the blade shapes. The one I really like is the binding strip die. The strips are cut with the diagonal ends. If you have a custom die made you can allow Accuquilt to make that die for others and if enough interest is shown it can become a new die for everyone to buy. One member had the Cleopatra's Fan block made for a die, one had music notes, one had magpies. I can't remember all of them.
