In an effort to save the environment AND to look good while doing it. I love this idea from the Blog - One Pretty Thing. It is a reusable cup sleeve for disposable cups. (vs. cardboard ones)
I printed the provided template, but, had problems with the execution. I then found this template from Somerandomdude.net That template seemed to work better. I did find it a bit narrow though so I cut my wool felt a little wider. Of course I had to add flair to mine. This is what I ended up with. Feel free to take this idea and run. You can make one in under 15 minutes if you have wool felt on hand.
