Are you selling items as a vendor or are the sales from items going to your church?
My church also has a craft fair, and after quilting many of the items you listed, and not having the items sell because they thought "they are priced too high", I decided to take a different route.
Our church has a silent auction as a part of our craft fair. Instead of putting items in general sale, I've put them in the auction as handcrafted, one of a kind quilted items. I've only once had an item sell for less then listed. Most have gone for my suggested price or higher.
