Shower Ideas: Help!

You guys, my sister in law is having a baby and she is letting me plan and throw her shower!!!! ZOMG I am going to be an aunt!!!!  I am super excited about this.  We have a place and a list of people, so we're on our way.

Here is my problem:
I am trying to match the feel of the shower to her bedding, which she loves, and which is adorable.

bedding from Target

Dots!  I love it!
The baker we are getting our cupcakes at has this awesome thing where the put these little sugar dots on top of their cupcakes, so I am hoping we can custom order something with the right colors of dots.

And I think I found some invitations on etsy I could buy that would be really awesome and in theme.

But I need favors, you guys!  Something Mod and dot-having and something that's not totally lame and that you'd like to take home from a shower.  Help!  I'm not awesome at the favors stuff.

I would also love to hear ideas for DIY centerpieces we could do with lots of awesome dots.  I was wondering if a cookie bouquet of different sized circle sugar cookies with brown/blue/green colored icing would be nifty or a little overmuch on the sweets.   I think it could work.
