My assistant manager at work had asked me to help make part of his study unit for Medieval England in school. He is dressing up as a monk, will make a presentation and conduct an interview! All he needs is a rosary that looked medieval-y enough. I hadn't seen the costume itself, but he assured me to think of 'a Jedi robe'. Either way, I think I had some success. Take a look!
What you're seeing is hemp twine knotted with dried bean and wood beads with a small wooden cross. There's a simple loop that can be slipped over a bean to keep the necklace safely on the neck.
Can't wait to see the finished result of the full costume!
