Size #75/11 arrives with most commercial embroidery machines. Reserve this size for heavy caps.
Size #70/10 produces sharper lettering and details in most of your embroidery work.
Size #65/9 is general used with 60 weight thread for fine detail and outlining of small designs. This fine needles are also appropriate when sewing on fragile fabrics.
Size #90/14 works well for heavier 20, 30 or 35 weight threads such as Madeira's Supertwist or FS20
Size #100/16 are needed when sewing with yarn weight threads such as Madeira's Burmilana
Universal points are somewhere between a sharp and a ball point and are best for the standard needle to use in your machine. Switch to sharp points when sewing heavy bags or dense caps. Use true ball points when sewing on fine knits or sweaters.
When sewing leather use the finest sharp point available. Holes made by needle penetration of leather do not close up as fabrics do.
The finer needles will make smaller holes that the threads will fill.
Reserve "leather needles" with triangular points for sewing on heavy leather such as belts. Do not use this heavy needles on fine jacket leather.
