Step 1:  Put wig on wig head and mark off areas of color.  This is a tentative, not exact, guide, so don't worry about getting it perfect.
Step 2:  Cut braid in half.  Cut one half in half again.  This length is sufficient for sides and ears.  Cut this section in half one more time for lengths sufficient for bangs and back.
Step 3:  Knot hait in half.
Step 5: Apply small dab of hot glue to wig cap and attach knotted area to glue.
Step 6: Repeat steps 2 through 5 for each color until your wig is complete. Use longer fibers for the wig flaps and ear area (see step 12).
Step 12: To create ears, take a pile of longer fibers and bunch them together, securing them with a clear mini ponytail holder.
Step 13:  Trim and style the wig using a pair of small bathroom or sewing scissors.  Since CATS wigs vary for characters and productions, it would be difficult to write a tutorial for shaping.  Use good judgment, and find as many photographs of your character’s wig as possible for reference.  It’s tempting to go scissor-happy, but cutting a little bit at a time is always wiser than one big stroke.  Feathering (similar to cutting a fringe on paper) will give the wig a more natural look than straight cuts will.  I like to cut a small triangular area away from the wig where it sits at your temples; it squares the face like authentic wigs do. When you are finished, you may see areas that need extra coverage.  You can cover these areas using extra crepe wool with a dab of hot glue.
Step 14: Use styling wax to sculpt stubborn fibers into place, then spray the wig with maximum-hold hairspray.  Let it air out for several days before use or storage.
An excellent hairspray is AquaNet Extra Super Hold, available at retailers such as Wal-Mart, hair salons, and beauty stores.  It provides a stronger hold than other hairsprays. Be sure to brush your wig as you spray to avoid droplets forming on the wig fibers.
