I had a spare vase (really a vase, since all my vases could be considered spare) and some whole coffee beans I liked the smell of but not the taste of. They just weren't oily enough, but they had a soft, pleasant coffee smell.
One day while being frustrated about not having a good way to dry the kids' paintbrushes and while doing major cleaning, I decided to throw away the beans I just wasn't ever going to make coffee with, and BAM! I was struck with Good Idea Number 13,683...or so. I could put the beans in the vase and stick stuff in there to dry!
It works great, when I shove the wet paintbrushes and straws (like the hard kind that come with re-usable smoothie cups) in there, I get a quick whiff of coffee. The items dry very nicely. It's pretty enough for my...decor. It's simple. It doesn't take up much space. I love it. Happy to share it with you.
