I recently joined a custom cards group on Facebook called Custom Baseball Cards. The group is actually for all sports but it's been very heavy with the baseball since I joined. So as my introduction into the group I made a mosh-up of baseball in the OPC hockey style. Obviously, I had to go with the two Canadian teams. Since I posted them here, I figure I may as well add it to the blog.
If you know of any active custom card communities, or blogs, especially hockey, drop the links in the comments.
