Feeling like you might be in a bead shape rut? How about looking to non traditional shapes that are right in front of you? There are books all over the internet that would work beautifully, and one of my choices includes books on perfume bottles. Just think of all the gorgeous shapes waiting to happen. Using these beautiful shapes as inspiration doesn't mean that you need to make perfume bottles too, borrow the shapes and see where your imagination will take you.
(And then of course, show me, because I'd always like to see what you do!)
