Cast off leaving a long end on one ear.

Making Up:
Sew row ends together and turn the mouse to the right side. 
Sew the little ears in place – use the one long end to embroider the nose. 
Use black wool to embroider eyes. 
Use some suitable coloured wool for the whiskers – I stitched through the face – leaving an end, secured the wool and left the other end at the other side.  Cut the whiskers to length and unravel the wool strands. 
Make a twisted cord for the tail – before allowing the cord to twist on itself, thread it through the back of the mouse, when it twists, it will secure itself to the body, and you just need to knot to the right length and cut off the excess.
