@yaytoast29 Hmmm… the exact measurement depends on how long you want the collar to be, as well as how long a 12-string bracelet you can make with your usual string and length. I don’t use DMC (in fact, I usually use a lot of no-brand string) so I can’t give you specifics. I’d recommend figuring out your desired length, then making like a test strip with the string you plan to use, and then do some mathing/calculation from there.
@minutcraft I hope you don't mind that I made a pattern when I reviewed the commend by 6741. If you mind, I can request for it to be taken down, so you can post it.
@6741 that is technically possible if you add 2 more layers of arrowheads—which means widening the pattern and increasing the number of strings from 24 to 32
