being a quilter is not the same as being a seamstress.
being a seamstress is not the same as being a quilter.
the two activities use a few of the same tasks, but often not in the same way or in pursuit of the same type of finished item.
trouser hems are a pain. the best way to get them right is to pin them up while the person is wearing them. (to save wear and tear on your back, have the person stand on a sturdy stool or level chair so you don't have to kneel and crouch to see what you're doing.)
once they are pinned, turn them inside out. measure along the fold to mark and trim an even hem allowance and to get rid of the frayed bits.
to avoid fold marks, attach seam binding.
if your machine can do a blind hem stitch (most can), refer to the manual to see how it's done.
otherwise, it's best to hem by hand. space the stitches about a quarter inch apart. catch only one or two threads from the outside layer with each stitch.
if they are not
your pants, my advice would be to hand them back to the owner and tell them to surf the internet for instructions. [mmmmwwwwaaaahaaaahaaaaaaaaaa]
