Super Simple Tea Cosy Pattern Generator

It's super, it's simple, and it'll keep your teapot warm for hours
Here it is, the Super Simple Tea Cosy! I've knit a few versions; this pattern is both easy to memorize, and easy to customize. The one above was knitted in handspun longwool; the one to the side was knitted in colors. The color patterning is NOT included in the pattern, but adding it is simple. All I did was knit odd stitches in one color, even stitches in another all the way across the row. On the next row, I knitted color A stitches with color B and vice versa. Every four rows I changed one of the colors for a new one. You don't have to do color work; you can just knit solid. But I will say that carrying two colors across the row like this makes a thicker, warmer cosy. Use wool or wool blend yarn if at all possible.
