Microtex or sharps machine needles are perfect for straight stitches on delicate and microfiber fabrics. Recommended for patchwork fabrics.
Needle style should be considered when your starting your project.
The right needle for the right fabric and thread will improve your stitch quality.
A packet of machine needles is a small cost in the grand scheme of keeping your machine happy.
Machine needles should have a sewing life of eight hours and should be replaced when this is exceeded. This will avoid fabric pulls, frayed threads and skipped stitches.
