Colour in the circles on the template, and cut them out

Fold the 8 large circles in half, with the coloured part on the inside

Take 2 of the small circles and glue plain sides together. Repeat the process for the other small circles. You now have your ears

Take 4 of the large circles, glue on one side, and attach to the next large circle. Repeat 4 times

Once you have the first 4 circles glued together, attach 1 ear. Glue the remaining large circles together, and add the second ear, lining it up with the one already attached

If you want to be able to hang your mouse add some string down the centre, and seal the mouse together. Now add him to your tree!
