705ZWIMETX3.0/90 SCHMETZ TWIN METALLIC 3MM SIZE 90 PACK OF 1 CARDED
Twin needles are actually two needles mounted on one shaft and are used to create two rows of stitches at the same time. When using a double needle, two spools of thread will be used in the top of the machine. Pass the thread from each one on a different side of the tension discs and thread one into each needle. Only one bobbin thread will be used and the stitches will create a double "web" of stitches on the back of the work.
The package of needles will show two numbers. One is the needle size; the other is the distance between the two needles.
Your machine should have a zigzag capability (with transversal hook) and a needle plate that has a hole wide enough for the needle. If you have different needle plates, use the zigzag stitch needle plate. Make sure to use also a zigzag foot with wide hole and not a straight stitch foot.
