Here are 2 patterns to create characters from Star Wars.
Darth Vader comes with a separate helmet and cloak whilst
Baby Yoda has a separate coat (see photos). Knit on 2.75mm straight needles in DK yarn, tension is not crucial.
Baby Yoda uses around 22g green DK (17g beige for the coat)
Darth Vader uses 44g black DK plus a few metres of grey and red.
