My wife has quite a garden, so I put these things up all the time. They are kind of a pain to get to look decent by hand-- nice straight runs, level, without too many squiggles and bends in the wire. With the right tools, you can put strong, braced corner posts, and stretch the wire really tight. By hand though, you are limited to just making do...
- You can sort of tie the ends together without much trouble, and you'll never see the seam. Use some wire cutters and snip some loose ends on one piece, and just wire it to the other.
- Put in T-posts with a sledge hammer, trying not to clobber the top too much. If your ground is as rocky as ours, you'll have to try 10 different places before getting the thing sunk two feet or so down without hitting something big.
- String it up, and pull as hard as you can while a second person fastens it to the posts with some wire or zip ties (black UVproof kind) or whatever. For pulling, you can thread a wooden or metal bar vertically through the fence end, and use that to pull on. Use a winch or something ifyou have it.
- By the sound of your message, you are probably best off just buying a simple garden gate with hinges at a garden store. I make my own usually. Gates are my existence's bane. Or something.
