After I had my Intuos for a couple weeks I realized that having it sit in the open on my desk would greatly encourage dust and other yuckies to form on top of it or in the cracks. I knew I could buy a case for $20 but what fun is that?
I am definitely not a seamstress by any means and my measuring was a bit off. But I used some buttons that were lying around and made loops to fasten it down when I'm not using the tablet. Other than it being too short, I'm fairly pleased with how it turned out.
The bottom has a cardboard base which is lined with batting as well as the top flap. My original plan involved a zipper, handles, and having the buttons on the inside to secure it open, but plans change and this works just fine for me.
