When I bought a new car the dealer told me to use only Shell gas. Do u think I believed him and did it. ....lol. If you believe that I wonder about you. Now think of it this way. What needles were used in Janome machines before they started branding their own. There is a reason some needles are called Universal. I have to chuckle about some stuff we quilters are told we have to use or do. Guess I should start using only Correlle in my microwave. Makes me wonder if they designed the machine to fit the needle or needle to fit the machine. If we put a Janome, a Bernina, a Schmitz needle side by side under a microscope they would probably look the same.
