Repurposing

I have a collection of salt & pepper shakers - some have lost their partners. I've been thinking of how I can repurpose them. My brilliant idea was to drill the holes a little larger and glue the stopper into the bottom in a permanent fashion so that I could use them as a bud vase. How cute would they look with a few long stem flowers coming out of them?

Unfortunately, this leaves me with the dilemma of how to get the water in and out. Maybe a slightly larger hole near the top hidden in the back would do. If anyone has an idea, post a comment. If your idea works, I'll make one for you :)
