Side winder versus pre-wound bobbins
I would just like your opinion, one of my Patchwork group is hoping to get a Sidewinder deluxe for Christmas, a combined pressie from her children. I have been reading up on this and found mixed reviews so I was wondering about the use of pre-wound bobbins! I have always wound my own and have taught my ladies to use the same thread in the bobbin as their top thread yet most of pre-wound bobbins are in polyester, why?
Thanks in advance for your thoughts.
