In case you don't know about Sugru, it is a new and interesting material with many qualities and just a few drawbacks: the main quality is that it's as easy (and fun) to use as play doh, but it also bonds to almost anything, does not shrink when it cures, it remains flexible, waterproof, and dishwasher proof once it cures, plus it is heat, cold and UV resistant. The cons are that it is not food grade (meaning you can't use it on anything which will come into contact with food) and it has a limited shelf life -- a few months, not a few years. This is really too bad, because it would be great to have around for odd repairs. Instead you will need to order it online (I don't think it's sold in stores) when you have a specific project or repair in mind.
For this necklace I used two 5g packs of sugru.
Step 1: Wire Foundation
Form it into the proper shape around your neck, then use pliers to make one end into an eye, and the other into a hook.
Step 2: Apply Sugru
Next place your shells, a few at a time, in place on the sugru covered wire. Use a second pack to attach the shells from behind. Reinforce the super thin shells with plenty of sugru.
If necessary, break your shells with your fingers or pliers so they follow the curve of your wire.
Step 3: Cure the Sugru
Curing Sugru 3mm thick takes about 24 hours. If the temperature is below 21°C (70°F) or if your piece is thicker it will take longer to cure.
Step 4: Apply Glue
Simply cover them with a thin layer of regular white glue. Not only will it dry clear, it will also make the shells shine even more.
