You only want to use a 60-100 wt in the bobbin, wether prewound or not. This is for embroidery only. You won't find a thread that thin in cotton, not near strong enough to be that thin.
There is no reason not to use a poly prewound in your embroidery, or even in your sewing machines. Try a break test... take 18" of a cotton sewing thread, and 18" of a 60-100 wt bobbin thread and break them...it will take as much or more strength to break the poly bobbin thread as it does cotton.

I have a Janome 4800QE and have yet to see pre-wound
plastic bobbins with
100% cotton thread. I'm kind of reluctant to use cardboard-sided bobbins and, besides, I really don't want to use poly thread in the bobbin if I'm using cotton thread on top. What has your experience been with pre-wound bobbins? Thanks everyone!! I'll be waiting to hear from you.
