I'm pretty well versed in using Adobe Illustrator and Photoshop, so making signs etc. is pretty easy for me. So, to answer your question about how hard it is to make a sign like that, I would say it would be very difficult for someone without a graphics background. As I've told others, making things like this is kind of a hobby/stress reliever for me. I enjoy doing it alot. If there's something you need made, don't hesitate to contact me and ask. Sometimes when people give me an idea for something, I end up printing one for myself.
