I adapted each chart by adding rows above/below and left/right so that they all ended up with 34 stitches across and 42 rows tall. These worked well in addition to some other Charts I found online.

For General Grievous I used red yarn and did a French knot to give him red pupils.

Additional Star Wars charts.

I used these in addition to charts found at Star Wars Craft Charts to make a blanket for my son.
