Here is a little something I thought of and made while looking at my scrap pile. I was working with some draftboard and I had the thought of making something for my vehicle for scents. I struggle trying to find a scent I really like, and I hate how the vehicle scent devices limit where you can point the vent sometimes. I came up with these. Draftboard is more absorbant, so that combined with your favorite scented oil, and you have a scent you like in your vehicle. I know it is a silly little thing, and after making mine, I see others have discovered something similar. I thought I was on to something. 
My wife immediately named them Makes Scents, but I did a search and see that is a thing already too.
Thanks for checking these out.
