SoE uses two stakes per yard and one binder per stake with two extra at the beginning and end of each run.
Achieving a neat finish with SoE is easy with a few simple rules.
1. Place every stake at exactly the same spacing - every 18". To achieve this my holly mallet which I cut from a tree, has a shaft of 18" so when I'm knocking stakes in I use it as a distance guage.
2. Get the stakes in a straight, or regular, line wth no kinks and wiggles. This is harder. It is natural to eye each stake back against the line you've already knocked in. You swear they're perfectly in line but when the job's finished it looks like a dog's hind leg. As well as lining them up with those you've already put in, every four or five yards you need to walk back down the laid hedge and eye the line of stakes forwards against the hedge you've yet to lay. They should be heading for the centre of the unlaid hedge at all times. If they're starting to veer off to one side, you won't spot it and you'll automatically correct the course without thinking about it and so introduce a dog-leg. Walking back down your work every so often and eyeing them up the hedge as well as down helps to stop this happening.
3. Make corrections before you set the binders. Some stakes will be pulled out of line by pleachers under tension and no amount of fighting the pleacher will get the stake to stay where you want it. Wait til you're well past this troublesome stake and the hedge is woven in on either side, and very often you'll find you can pull it out and reposition it without the pleacher springing out.
4. Adjust the stakes when the binders are in place but not dressed down. Few stakes are ever perfectly straight. With the binders holding them steady you can often take out a minor kink just by turning the stake in its hole without pulling it out.
If I get a really wayward one that can't be pulled out without springing the hedge, I'll ocasionally snip it off just below the top of the hedge line and put another stake in next to it in the right place.
