A third hand would be a great tool to help you with the curve created as the jumprings are brought together. Position the clips on the third hand so they hold jumprings just far enough apart that you can work a new jumpring into the weave. This will also help keep the rings in their proper position--which is important as the design evolves.
The magnifier that is also part of the third hand would be helpful when making sure the seams of each jumpring are closed securely.
