Insert this line here:
contributor_list = [c.pk for c in contributor]
> form = SmallDesignSetSaveForm(initial={

'contributor':contributor_list

Also, as a matter of good practice, you should consider naming
ManyToManyFields in plural. So, in the above case, the field would be
SmallDesignSet.contributors instead of SmallDesignSet.contributor.
