Another So Fine fan here only thread I quilt with. Three cones came with my Handi Quilter so I know they reccomend this thread too

This is my 'go to' bobbin thread in my longarm. I also will use it on top when I want a thinner thread. (Most of the time I use Signature cotton on top as I like the look of a little heavier thread.)

I have a friend with a Tin Lizzie LA, that is her go-to thread for her bobbin also.
