That is interesting. Both of my Bernina's have both vertical and horizontal spindles. At the master class we were told to put the crosswound thread on the horizontal thread spool holder and the others (I think it is called stacked - like coats and clarks) on the vertical. I wonder if it varies according to sewing machine manufacturer? The website I referenced earlier says that the crosswound should come off the top, which it would if it were on the horizontal spindle, and the others should come off the side, which it would from the vertical spindle. Bottom line is, whatever you are doing, if it works for you why change? ;-)
