This is the smallest size of twin needle. The needles are size 70 (11) and they are 1.4mm apart. It is perfect for decorative sewing and free motioin work.
It is also used for stitching narrow pintucks with the pintuck foot, usually a 7-groove.
For more information on which needles to use for different sewing tasks, please refer to our free Guide to Sewing Machine Needles, which can be downloaded from our website.
These are the standard 130-705H class (also called 15x1) domestic sewing machine needles.
And here's the tedious (but important) bit: They will fit all Singer domestic zigzag machines and almost all domestic zigzag machines made in the last 60 years including, Brother, Jones, Janome, New Home, Toyota, Bernina, Juki, Frister + Rossmann, Elna, Pfaff, Husqvarna (Viking), Jaguar, Novum, Britania, etc.
They have to be zigzag machines because the witdth of the twin needle needs a needle plate with a slot rather than a round hole.
