Bobbin thread problems M7

Sally Silvers

Glide is my go to thread on my Janome Horizon 8900 and Tin Lizzie longarm.  I've never had a shredding problem, so I would guess you have a tension issue with your bobbin.

I have run into a problem using Glide thread on the bobbin as it tends to shred.  Is this a problem with polyester threads in general or just GLide?
