This is a simple bracelet design useing aluminum and rubber jump rings rather than my usual copper.
Rubber rings have some good potential uses, but really take some getting used to since I can't open them up like I would normal rings. However they do make for more tight designs thar can take more punishment from the wearer, lower weight so they don't feel so cumbersome.

The biggest cons i can foresee however, is one has to have a very good idea what they want to make and know exactly what size metal rings they need for them to work with whatever design you have, replacing a broken rubber ring would require more effort to some extent. Other than that I think I'll be experimenting with them more in the future.
