I really like the bubble necklaces.
I also ike the idea of making my own, and I found two relatively easy ones on Pinterest. The upcycled tie and the washer/ribbon necklace. The Pin also suggested using nail polish to jazz up the washers. I'm not sure if either would qualify as statement, but I think they will make a nice addition to my very limited collection. I just haven't found any I like in the stores here (yet).
There is also organizing right now they are all jumbled in a box, and they obviously get tangled. I really like this idea (also found on Pinterest).
Do you have any statement jewelry?
