Today’s tip is about where to put the thread on your machine. Most machines are designed with at least one vertical spool holder and one horizontal spool holder.
Thread that is wound with a pattern (like Aurifil) works well on either spool holder.
However, thread that is wound straight (like Sulky and YLI) needs to be on the vertical spool holder.
This will make for much happier thread which means smoother tension and less breakage.
