I am trying to help out a dog trainer by making some dog leashes out of Biothane. I bought a Reliable Barracuda and was sure it would sew the Biothane. I am using #69 thread and the right needle but am still having trouble sewing it. I keep having issues with the bird nests underneath it and it will sew on top but underneath seems to be where I am having issues. I think my machine will sew it but I am doing something wrong somewhere that I am having issues. I am hoping someone can help me so I can get these made for the trainer. Thanks.
