amicus, your experience is unusual, ask them to replace it with another bigshot and you should be fine. Mine are years old with no problems coming apart.
sos, I don't have any pics, but I just use a stitching/lacing leather punch, punching holes along the existing stitches on one side, and then stitching the leather with B-50 or fastflight string (for the strength/small diameter) You could also take the glove to a shoe repair shop and have them stitch along the existing stitching. You usually don't have to take up more than 1/16" to make the glove fit nice and tight.
