3 color intarsia chart by ifdefelseif can be used to make a scarf or other item.

Size of finished item will depend on yarn weight.
I will use fingering weight.

If you want to knit it from worsted or bulky and hang it from your 20-feet wide balcony, ask permission from the homeowner’s association first.

Hint: Start it at the narrow side where the “n” is, and work the shorter rows back and forth. This way, it’s easier to carry the Black for the sheep, too. Work the “3” last. When Ravelry hits 4 million and the numbers need a touch-up, knit up an additional pocket with the correct number and sew that over the outdated “3”. Do this every year.

It is safe to assume that we don’t need to save space for a two-digit number.

Happy knitting!
