SARAH’S ALGORITHM
You may have noticed the awesome Stargazing
project in 2018, where Sarah Spencer, an
Australian software engineer, not only knit this
super-impressive large-scale tapestry — 9 feet
by 15 feet! — but came up with her own algorithm
for 3-color DBJ to do it (Figure

). She can knit
any arbitrary 3-or-more color pattern without
color conflicts, with a minimum number of extra
passes, and keeping to an ABC order. As far as
I can tell, Spencer’s technique is new. She has
kindly posted it as open source code on GitHub
(github.com/chixor/knitting_machine); you can
follow her work at twitter.com/HeartOfPluto_.
