Yes, my new toy from the Husqvarna dealer is a Specialty Bobbin Case:
I have wanted one of these since they were introduced but never had the opportunity to get one till this week. I just need to get some fabric and stabilizer, and find some time to play. I have several threads options. The best part is this will fit all three of my Husqvarna machines so if one is busy it can be used on another one. Yes, I know having three of these machines is excessive but when your offered $100 for trade-in I think you would turn it down, too.
If anyone knows of any instructions for bobbin work, please let me know. Husqvarna's instructions are bare minimum. I thought that they might have some projects using bobbin work but couldn't locate it. Any help would be greatly appreciated.
