I've just got this working so will post the answer in case it helps someone else.

You can pass the ID of the item you'd like to edit in urls.py like this:

(r'^projects/edit/(?P[-\d]+)$', ProjectWizard.as_view(FORMS)),

You can then look up the item with following code in

views.py:

class ProjectWizard(SessionWizardView):
    def get_form_initial(self, step):
        if 'project_id' in self.kwargs and step == 'project_essentials':
            project_id = self.kwargs['project_id']
            project = Project.objects.get(id=project_id)
            from django.forms.models import model_to_dict
            project_dict = model_to_dict(project)
            return project_dict
        else:
            return self.initial_dict.get(step, {})

You need to convert the model to a dict so you can set it as the initial data.
