This uses moss stitch and two colours.
The colours are used in pairs of rows, like the stocking stitch pattern. But the rows are knitted as described below.
I have not done a left-handed version of this. If you are left-handed, imagine the pictures as after you have turned the knitting round, to start the next row.
Here is how to introduce each ball of wool. As it is moss stitch, first row is alternate knit and purl, then second row is alternate purl and knit, and so on (regardless of which colour is used).
Make sure that you don't get the wool of the different colours muddled up! They are rather apt to get twisted round each other if you aren't careful.
This produces an interesting mottled effect. Both front and back look the same.
