If I were to begin right now it would be with the clover devouring my yard: the toe would be the light yellow clover flowers with a soft green foot in st st for the clover leaves. At the ankle would begin the light grey bark of the crabapple tree in a rib stitch. It would grow up my leg until it hit a soft blue sky and I'd so some simple fair isle pattern to fade the branches into sky blue.
You could custom dye a ball of yarn to knit up this way. Or, you could tie bits of yarn together and wind it into a ball. The best part would be designing a label with directions and the original scene that inspired the yarn. This would make a great Lenten project - using stash and leftovers to create landscape socks, mitts, tea cozies, neck warmers.... waiting for Spring.
