This step is optional but will allow you to create a miniature felt mouse which can be posed in many positions.
To make the armature, cut the two pieces of wire according to the directions on the plan. One will be roughly 6 1/2 inches (16 cm) long, the other will be roughly 8 inches (20 cm) long. Fold the longest wire in half, making a loop at the halfway point. Twist the wire once or twice below the loop to join the two wire legs back together to form a neck. Spread out the two ends of the wire.
To add the arms securely to the armature for the miniature mouse, lay the arm wire across the body and head wire from the previous step, setting the wire for the arms just below the twisted sections for the neck (see photo). Twist the arm wire over the two ends of the main body wire anchoring it securely as shown in the photo. Proceed to the next step to finish the armature.
