Are all sewing machine needles interchangeable?
Except for in some antique sewing machines, sewing machine needles are universally interchangeable within all sewing machines. If the bobbin is at the front of the machine, the flat side of the needle faces the back; if the bobbin is at the side of the machine, the flat side of the needle faces right.References:Denver Fabrics: Sewing Machine NeedlesThreads: Preventative Sewing Machine MaintenanceMrs. Parker’s Millenry and Mercantile: Replacement Shuttles, Needles…
