Is the paper made as well? One thought on homemade cards that are not on traditional paper and or something that will not feed in an inkjet system of some sort is to design the information you want and have a rubber stamp made it can be quite good if done well and gives a hand made look and feel to cards the other idea that is a bit more complex is have letter press type done and actually just emboss the paper it is beautiful (but can be hard to read depending on the paper and type and depth of the embossing) Just my passing thoughts.
