Hello, I have just watched the Winding bobbins video from Season 1, Episode 3. It doesn't show winding a spool with silk. I just bought some silk from JST for Season 5, Episode 5, Bronson Spot. I don't want to mess up my silk! Does Jane recommend winding silk onto spools just the same way she winds bobbins?

Yes, she does. A large Leclerc “storage” spool will hold 100 g. of silk if you wind the bobbins firmly enough - just like you do your bobbin.
