When taking the ceremonies of Jukai (taking the precepts) and Shukke Tokudo (home-leaving ordination), many Zen groups follow the tradition of sewing a rakusu (a small bib which is modelled on the full Buddha robe or kasaya/kesa, see image below) and full robe. This is, to my mind, a beautiful part of practice but we have had some members of our sangha who struggle with the fine motor skills required to sew so have either required some assistance or for another sangha member to complete the task for them, in an act of generosity. Other groups may vary in their attitude to this but I believe there is no reason to exclude anyone who wishes to wholeheartedly take part in these ceremonies and the responsibilities that come with them.
