I have been making these for a few years now. I have a few different styles available. Most of them are set up for 4 calls. The two drops on the sides are adjustable (or even removable) to make your calls hang where they need to be without clanking together. The bottom two drop are not adjustable. The part that goes behind your neck is done in a flat braid, then it changes down the sides to a round braid. The round braid is much more flexible and makes it easier to manuver your calls. The version shown in the pics is done in my Wide Neck style. It has an extra layer of braid to make it even wider where it rests on your neck. This version is $30 and $25 for the standard without the Wide Neck. Any questions just let me know.
Thanks for looking,
Guy
