My only experience with tying a quilt with our guilds donation quilt group. They were using some type of yarn. What ever it was it didn't want to be tied. And perhaps it was cut too short, I'm not sure. I volunteered to take the quilt home and do the binding. By the time I was ready to sew the binding, many of the ties had already come loose or untied so ended up tacking all of the ties in place with my machine. And I guess my point is, I'll avoid tying again.
