If you want to get more bobbins for your new baby, it sounds like your machine takes M size bobbins while our DSMs take L. I would try called Superior Threads and ask them about it - Bob has made it his business to know everything he possibly can about all the LAQM out there.
As for a thank you to the wonderful guy who gave it to you, if he is anything like my dad, the gift of single-serving frozen main dishes would be the most appreciated thank you!
Loving reading about your journey to get to know your LA!
