A few people have asked me lately whether the ribbons really stay tied. If you're anything like me, your tennis shoes come untied every 10 minutes unless you make a kindergarden double knot, so I understand the concern.
However, the ribbons really don't come untied on their own. Most of our ribbons have enough 'tooth', and the surface area of the knot is great enough, that it just does not happen. However, I do often tie a knot before I make a bow when using satin ribbons because they are a little slicker. So there you go.
