One of my Christmas presents was a Side Winder bobbin winder. I think I am really going to enjoy this toy, but the first bobbin I did was backwards. At first I couldn't figure out why it didn't load in my machine like my other bobbins, and then I saw the difference. (I use a Pfaff and the bobbin only fits one way in my machine. With the bobbin loaded correctly, the thread came out from the bottom of the bobbin and not off the top.)
I found that if I put the bobbin in "upside down" in the bobbin winder, it comes out the right way for my machine. The newly wound bobbin and I are sewing up a storm now.
Has anyone else had this experience? And what do I do with the bobbin that is wound backwards? Just pull the thread off or maybe pretend it is just a spool of thread for hand sewing??
