Animal Crossing Stitch

As I have a whole folder of medium and big stitched pieces, I want to stitch something more portable. Like charms or keyfobs.

So here is Marie from the Animal Crossing game (3DS). I used 16 count aida. I found the pattern in the numerous Hama beads patterns on Pinterest.

Originally I wanted to make a mini cushion, but I'm not really satisfied of the little Totoro I made a year ago, the character gets all out of shape.

So I cut the fabric around very close to the stitches like plastic canvas, and put some glue all around so it doesn't fray.

Now I need to add a back. I think I will put some felt, but will I stitch or glue it on?
