Coffee Filter Water Lily

So I'm working on my sisters baby shower and its sort of a sea theme.  Look at this gem I came across in my Martha Stewart Living magazine:

These beautiful coffee filter water lilies are going to look great on the blue tablecloths already in place.  And best of all - they're easy enough to make that the kids can join in!  They're going to love making these.  I mean, it's really as easy as color, cut, and glue. Here's the instructions, but really, how much more straight forward could it be?

Have you tried these?  Or any other coffee filter flowers?  I'll have my finished product up in a few days and we'll see if they turn out!
