Honestly this is what I do. Wherever I go I leave a business card. I sign myself up for as many art shows as I can that are local. Social media always helps as well... So I would get a facebook, twitter, tumblr and instagram.... You just have to stay active with it.
Where I am from there are not that many leatherworkers so word travels fast.
So thats what I do and it seems to be working very well.
