cedar stump w/blue bottle, for the porch

I want to get the front porch secured for letting Petra out there so I need to move the mail box off the porch and make a "gate" at the end as well as close off  the corner gap in the railings. With that end in mind I came up with the idea to use a weathered cedar tree stump I had to block off the corner. So- to add a little more to it, I mixed some mortar to add a blue bottle and some aluminum wire I might do something more with. Too much mortar mixed led me to make more "concrete" turtles. I have the new mailbox, but need to come up with a post for it, but not just any post.
