I'm mending my (second hand) leather gloves by hand.
My sewing skills are rudimentary, but I like fixing the seams of or patching up clothes every now and then.
However, I never know how to finish up a sewn seam. I usually just keep repeating the last stitch, alternating the angle a little bit, or the direction, in a random fashion (random perhaps because I reason that if it's hard for me to unravel, it must be so too for the thread itself).
I would like to know if there's a proper way to finish sewing a seam.
