A Elbereth Gilthoniel Chart
Not recommended for stranding due to very long carries at some points. Pictured hat was done in duplicate stitch; might also try intarsia.
Designed for a hat of 80 sts circumference, though you can take it down to 76 easily enough by omitting one empty vertical column from each space between words.
No particular gauge necessary--but then, you knew that. (Didn’t you?)
