craftgrrl | atomic molecular scientific felt bead necklace

so i've been working on this necklace all night and i am at a loss as to what to do with it. it doesn't look quite right to me yet. so far it has no clasp of any sort, and it's made up of three strands -- two green and one yellow. what do you think? any ideas? i like it, i just feel like it could be better!

here's a (kind of crappy, sorry) pic:

i think i'm going to try and braid it or twist it better so that the yellow strand mixes more with the two greens, it's just hard to do that sans clasp.
