Superglue might work but I'm not sure I would do it without antibiotics. The one time I waited to get stitches it was only about 12 hours and I got yelled at and antibiotics due to waiting. The power was out and we were having an ice storm and I chopped my thumb with the hatchet chopping kindling to get the woodstove going. Went in the next morning cause it was still bleeding. I guess chopping halfway into the thumb wasn't going to stop on its own.
