one button tutorial part 5 edge binding

Edge binding the infill cords:
Trim off the tails of the infill cords using a heavy scissor or wire cutters.

Hint: I prefer the diagonal wire cutters as these are heavy duty and can clip off multiple cords without fraying or distortion. Find these tools at a hardware store or borrow from your household tool kit.
 It's important to get a clean cut as close to the surface as possible.

Make another two or three crossings spaced about 1/8" apart. Draw the cords together and overstretch the nylon thread just slightly as you draw the thread through the cords.

Nylon is naturally elastic which means the thread will continue to compress the cords after you have placed the binding and drawn it through.

Continue edge-stitching back and forth using the nylon thread and pliers. Each infill cord should be anchored on each crossing. Tension each crossing   and work you way about half the circumference around the mold. Remove the temporary needles as you go.
Here you can see the progress of the edge binding. The heavier cord is positioned on each edge with the thinner cords in the center.

Hint: place an even tension on each crossing to maintain an even shape to the work.
