I know what a thread net is and does, but never used it before. I am using Mono.Poly monofilament thread and to keep it from getting knoted up and just unraveling I want to use a net, but my instruction booklet does not give instruction on loading it on the spool, I put the net on but the thread keeps knocking the net off. Do I put the net on before I thread my machine, or after . Can't seem to figure it out. thanks for your help.
