My Pfaff 130 (the machine I use every day) is named Leslie. Leslie was previously owned by a farmer named Leslie who bought him at a farm auction, because his wife wouldn't let him sew on her machine. Leslie only sewed denim quilts for his grandkids and charity. Now Leslie, the machine, sews everything.
The electronic Viking from the 1990's that I gave to my niece is named Lena.
I have yet to name the FW and 301.
