You need to know that the average pea plant is not at all bright and
will instinctively grow away from whatever support you provide. The twig
method doesn't work very well because of that.

Use the netting between two poles method. When the plants are about a
foot high and some are wandering, stretch string between the poles about
6" above the ground fairly tightly so was to put the wayward plants
towards the netting.
