I have a thought but this would require some time and effort from the organizer...
The organizer has people sign up for the prayer/family bracelet ( it may end up being a necklace! LOL! ) and says "okay, everyone send me 30 of their special beads". The organizer could then snap a picture or each bead and note who it represents.
For example...I pick out a special bead that represents myself. It could be something as simple as a 8mm Dark Blue Bicone bead. So I would send 30 of those.
Mary chooses a light pink and white swirled glass bead, she sends 30...etc etc
The organizer can then send everyone a set of beads. Then either pictures could be posted of the bead with the person's first name/BD name under it, or a simple list could be compiled with a description and the person's name/BD name and sent with the beads.
Then each person could create their own piece with it. Whether that be 3-4 bracelets or one bigger piece, etc.
Just my thought! But...like I said, it would take some time and effort on who is organizing it...
