Contest? Why not. Polyvore and Nordstrom are running a contest via Facebook.
Build a "dream board" of all the items you think represent your wedding (all items are obviously available at Nordstrom) link it to Polyvore's Facebook App. (you will have to accept their application) and enter for your chance to wine $1000.00 Nordstrom gift card.
Wanna see mine? VIOLA! (kinda upset that it didn't layout the way I planned, but whatevs- I'm entered)
