Step 4:

Cut (and Embroider):  Cut out hand pattern from the paper.  Test it against your hand and widen, narrow, shorten or lengthen as you need.  When it is the perfect size cut from the fabric.  Fold fabric in half so you have two layers.  Lay paper pattern on fabric and cut.  Cut two with thumb facing right.  Turn pattern over.  Cut two with thumb facing left.  If you want to embroider the top of the mittens, (as I have in the black pair of mittens), this would be the best time.  It is much easier to embroider on one open piece of fabric rather than getting your hand inside the mitten when it is sewn.
