Is Madeira classic 30(rayon) fit for a FSL (and what's the right bobbin thread) or can I use it only for embroidery? I like its shiny look very much.Thanks. Adriana

I think it would be perfect - go for it.

I use Madeira rayon 40 both top and bobbin. the 30 wt would make it just a bit thicker, which would be OK for FSL.

That is what I use for both top and bobbin for FSL.
