Use Schmetz Universal Twin/double needles to create two rows of stitching simultaneously. The distance between the two needles is 2.5mm. Both needles are size 75/11. Schmetz Universal Twin Needles are a creative way to add strength and style to your projects. Twin needles are the best way to create perfectly parallel stitching, for hems and pintucking. Replace Needles. Machine needles should be replaced after a maximum sewing time of 8 hours. Replace needles more frequently when sewing synthetic fabric, appliques or machine embroidery. This will avoid skipped stitches, fabric pulls and frayed threads. 1 needle per pack SCHMETZ_Needle_ABC_7
