Today, in midwifery school, we had a lecture and demonstration on suturing. Then we practiced.
I was delighted to learn that the sutures we use to "stitch" someone up are those one would use to stitch up a seam on, say, a sweater or cardigan - mattress stitch and blanket stitch.
Granted, I tend to like to knit seamless sweaters and other items in the round so as to avoid seams.
Needless to say, I need to butter-up on my sewing skills if I'm going to be doing this on perineums.
