A proper sewing job (WITH A NEEDLE IN GOOD CONDITION!!!) shouldn't cause any problems with fraying. A bad needle will cause damage to the fabric
, but a good needle will actually go BETWEEN the weave.
If you look at the tip of a good needle, you will see a nice point or ball shape. If you look at a bad needle, you will see a chisel, mushroom or other horrible shape.
A bad needle will sometimes, but not always cause a slight popping sound as it stitches. That's caused by the fabric
catching on the sharp nasty edges and jumping up and down with each stitch.
More than once, I've informed little old ladies that yes, actually you can CHANGE the rusty old dull needle that came with your 1950 sewing machine!!!
