I posted a sneak peek of this as part of a sketchdump back in May but only finished it recently. Back then there was just one mouse, but I always intended there to be three. I could probably go back and tighten up some areas, but I think it's time to call it done:
A shot with my hand, to show size.
And a rotation, because plump mouse bottoms need to be seen at every angle. =P
And finally a shot from above:
Merino & Corridale wool with what I assume are #32, #36 and #38 felting needles.
