It's hard to believe i've been making jewellery for about 8 years and had never made a bracelet with elastic. Elastic seems like the place people usually start. 
I do have some in my kit though 'just in case' - I was in the studio the other day and suddenly felt I had to make one. And why not.... I like bracelets myself (i'm a long standing fan of shiny and sparkly accessories) but I don't like jewellery clasps on my bracelets (except magnetic ones).
