For most wovens and knits. Use two different threads for shading and texturing effects for embroidery and topstitching.

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.
