Here's a couple of ways I've been using for 30 years or so to attach a Port-a-Wrap to a tree using a rope with no spliced eye. The rope is 5/8" double braid bull rope. The nicely melted rope ends are melted using a 200 watt soldering iron. It's a technique that requires a little practice to master, but well worth mastering.
1) A big eyed bowline is tied to the Porty:

2) The Stilson hitch (also called a Cow hitch with a better half) is beginning to be tied to the tree. Notice how the bowline ends up being quite a ways from the Porty:

3) The completed and ready to use Porty attached to a tree using a Stilson Hitch with a big eyed bowline. The Stilson includes the final half hitch. This knot is also called a 'Cow hitch with a better half'. Note that the bowline termination is behind the tree out of sight. It just worked out that way.

1) A second technique using no bowline at all. Requires more rope than my first technique. This technique can even be tied in the middle of a really long rope.

3) Getting ready to complete the Stilson hitch:

4) The half hitch that completes the Stilson Hitch. This half hitch is considered a part of the Stilson Hitch where with the Cow Hitch it is added and called a 'better half'. This attachment is ready for use.
