Everything is very simple - we remove the first loop with the crochet, we sew the last and the crochet together. ‼ ️Important! We knit the last loop according to the figure, if the front - front, if the wrong - wrong !!! Only in this case the edge will be the same on both sides.
This hem is suitable for any knitting, and the front, and the wrong side of the surface, and scarf, and elastic. Not as voluminous as the i-cord, but not as flat as a pigtail.
