This is my Wonder ful daughter wearing the Wonder Woman set I made for her for Christmas 2017.  .  She wore the set to work....at the Movie Theatre in town.  She was a hit!

The scarf is a cast on of the same number of stitches as the sleeve cuffs.  Follow the graph for the sleeves and change the colours as you please.  I knit the first and last 6 stitches of every row on the scarf to get a firmer edge.
