You see, you would think that no-one would sell something that was free elsewhere wouldn't you. However that is not always the case.
All of my previous work WAS free, making it easier for people to get it. The problem was that it was also easy for pirates to get it. This is a common thing in the papermodel community.
So, by selling my work I ensure that most of the people who come and get them are genuine. It's not about making money or I'd have higher prices.
I still offer some of my work for free, just not all of it. The Fett items I'm currently working on will be free to members here, the Halo pieces I'm doing and have done will/are free to members of the 405th forum. So if it were about money then why would I do that? I trust the members here not to abuse it by trying to sell the templates on. 
As for making my work widely known. I may still be fairly new here when it comes to my contribution, but my papermodel designs are fairly widely known. That was part of the problem.
Thanks.
