I am not having much luck searching for them myself.
You didn’t try very hard.
Like I said in my original message, I didn't even know what they were called, its hard to find something you when you don't know what it is. AND you don't have any idea how much time I spent trying to figure it out either. I appreciate your help, I just don't know why you have to make me feel stupid in the process.
That was found from a search for “t-shirt template illustrator”. It takes no skill in Illustrator to do a search, and none of the terms I used were very technical. Granted, you didn’t use the word “template”, but it is a common term for a file one starts with. Illustrator ships with lots of templates, as do many other programs, so it’s not a hard word to find.
