DIY Centerpiece Ideas

So I have been playing around with DIY centerpieces for a while and I think I know what I'm going to do...here's what I've come up with so far. World Market sells these lanterns that are nice and big- you can fit three candles inside and they are so cute! Here's what I was thinking of:

I was thinking of placing a few grey river rocks around the lantern with either tulips in a vase like above or a few more candles. I grabbed the rocks from a place down the road to try out the idea of placing rocks around the lantern, here's how it turned out:

I like it- of course I'd replace those rocks with smooth ones like these:

I think it will turn out well. :)
