I started making my son's necklace for his bullet shell. I decided to make a full Persian. I couldn't remember how to make a Persian and after 4 hours of trying I almost gave up. The last Persian I made was in silver about a year ago. I sudenly rememberd I had to change the pattern a bit for flexibility. I true full Persian chain is too tight for jewelry. This time I wrote down the changes I made. I don't think I will ever forget, but just incase I have my notes.
