I chose to include this bind-off out of the many picot bind-offs that are out there because these picots are very small and sweet.
This bind-off does tend to flare out and roll forward a bit because of all the picots sitting next to each other.
Blocking the edge will help a little. Soak it in water, squeeze the water out, and lay the bind-off flat. Take your fingers and shape the little picot points so that they lay next to each other as flat as possible.
