I can never remember which sewing machine needle size I need for which task. So I decided to find out and publish it here so that I always have it!
I found this nugget of information amongst lots of information about sewing machine needles and how they work here: http://www.threadsmagazine.com/item/3751/machine-needle-know-how
Here’s what Lydia Morgan, the author of the article, has to say:
When selecting a needle for regular sewing, start with needle size. European needles range in size from 60 to 120, which refers to the diameter taken on the shaft right above the eye. American needles are sized from 8 to 19 in an arbitrary numbering system, and paired with corresponding European sizes: for example, 60/8 or 70/10; the larger the number, the larger the needle.
Determine needle size by fabric weight. Choose a size 60/8 needle for lightweight fabrics similar to georgette or organdy; a 70/10 or 80/12 needle for medium-weight jersey, Lycra, linen, or calf leather; a 90/14 and 100/16 for heavy fabrics like jeans, vinyl, upholstery or canvas; and 110/18 or 120/19 for very heavy fabrics. After choosing needle size, match the needle point to your fabric. The needle type and name is usually determined by the characteristics of the needle’s point.
Now it makes sense! Especially that 90/14 stuff.
