How often should I change my sewing machine needle?
This is one of the MOST popular questions. Needle retailers will normally inform customers that changing of a needle should take place with every new project and/or with every 6-8 hours of sewing. I personally find it hard to know how much sewing I have completed with the needle, especially as I change between sizes and types.

So… I tend not to work with any particular rule, if I am starting a new very important project I might use a new needle, this is more important when working with lightweight fabrics (to avoid puckering the fabric). Otherwise I tend to test the needle on my fabric and visually inspect how it performs. Take the needle out of the machine and check the tip if you are worried, it can also be a good idea to check that the needle isn’t bent. To check this simply lay the needle on a flat surface, it should lay flat!
