Hi everyone, I've entered into the exciting and overwhelming process of getting my boyfriend some paper models for Christmas, and I am thrilled to find out that I can print them for free. What kind of paper do you suggest? And do I need a fancy printer? Also, how do I print a pdo? I went on online casino paper crafts buildings at e-cardmodel.com and still couldn't figure out how to download the program. Thanks in advance for any help you can offer.
