These Organ 15x1 household needles are made for most domestic sewing machines. They do fit some sergers, embroidery machines, and quilters. If you are unsure of your machine needle size then you can always check your sewing machine manual. These needles come in both sharps (for woven fabric) and ball point BP (for knit fabrics). They are your standard universal style needles and serve most sewing projects extremely well! The needles have a flat back to them (and in most cases) the flat side of the shaft of the needle goes to the back of the machine. As for your machine's needle threader, sizes 75/11-10/16 will work the best.
The sizes listed are:
70/11 - Very lightweight/sheer fabrics
75/11 - Light weight fabrics
75/11 BP - Light weight knit and stretch fabrics
80/12 - Light/medium weight fabrics
80/12 BP - Light/medium weight knit and stretch fabrics
90/14 - Medium weight fabrics
90/14 BP - Medium weight knit and stretch fabrics
100/16 - Medium/Heavy fabrics
100/16 - Medium/Heavy knit and stretch fabrics
110/18 - Heavy weight fabrics
125/20 - Very thick and heavy fabrics
These needles are sold in units of 10 needles. Some packs have 10 needles per pack, and some have 5 per pack, but they will always be sold as 10 needles total so that means that if it is a 5 pack you will get two 5 packs.
