Does anyone have directions on how to make the knotted, not braided fleece dog tugs. I saw one on Etsy and I just love it, but that person doesn't seem to be willing to share how they made it. It looks like a four strand braid but it says it is knotted not braided. I make the braided ones for the dogs in my family (there's a lot between all of us) and these looked to be much sturdier. I thought maybe it was kumihimo but she said it was not. Any help is greatly appreciated. Thanks.
