Schmetz Microtex needles have a very slim, sharp-point for use with microfibres, polyester, silk, foils, artificial leather, lining taffeta and coated materials including oilcloth. The very thin, acute point creates beautiful topstitching and perfectly straight stitches for quilt piecing when precision is important. Note that the 60/8 size has a reinforced blade. 5 per pack.
