Schmetz Stretch Twin 4/75
Two stretch needles mounted on one shank create two rows of stitches simultaneously. Use on elastic materials and highly elastic knitwear.
How to choose machine needles:
Choose your needle TYPE based on your fabric type; woven, knit, silk, denim, leather, etc.
Choose your needle SIZE based on your fabric weight; a smaller number for finer fabrics and a larger number for heavier fabrics.
The standard size shank will fit into nearly every machine.
