Hello and thank you for submitting your question. I am very sorry to hear the news about your friend. It is very kind of you to look for this type of information to help her. There are individuals who, out of their own benevolence, can sew and handcraft custom made bags with various and materials. You may inquire with the social services, nephrologist
nursing staff at the treating hospital or clinic if they are aware of such individuals or services. It may help to reference that sometimes these individuals also make handmade/custom sacks for colostomy
bags. Of course, all of this is very dependent upon local resources.
All the best,
