Your new serger
I also have a Babylock serger & know exactly how you feel. I used to have Singer's Quantum 5 thread serger & it was an absolute nightmare to thread, especially the 4th & 5th Lower threads. OMG the Babylock is a dream. Here in Canada they are VERY pricey but I got it on sale & they took my Singer as a trade so I saved a few $'s there.
I still mostly tie my threads on but the option of threading itself is a dream come true, especially for those of us who are getting older. Good luck & I hope you love it as much as I love mine. Congrats.
