As a rule with any accident or health concern, seek professional help. The Urgent Care/After Hours Clinics/MedCheck's are less expensive than a visit to the ED, and usually faster. ($65 for the visit if uninsured at some and hours of 7am-11pm make it much easier to get in)
My dad is old school and growing up I've watched him sew his own hand back together on more than one occasion (you would think he'd learn). From being a parent, I've found that if there is no reasonable risk of infection that steri strips are very easy to close a wound once the seeping has stopped. Had one of the kids get bit by a dog a year ago and we took her to get checked out, the physician used steri strips just like I would have, but she benefited from a good antibiotic. We aren't in a SHTF scenario so it's time to get medical attention from professionals and then closely watch what they do and what they use and LEARN from them.
