I am in total agreement that instructions shouldn't be necessary for such a project. I'm just not in the market for a kit. I almost always make templates for my projects to facilitate reproducing them if I choose to do so. I just prefer to use my own designs, as simple as they may be. If I was inclined to sell my templates I would certainly include some directions. Not that hard to do. The more information you provide the customer the more they are inclined to buy.
