Virtually any darning stitch can work for snow. I favor straight darning stitches and today's stitch is a recent favorite. (Here is a refresher on darning stitches.)
The gaps in the row with stitches over three rows are a great opportunity to show off any shading. Remember to always start from the far side of any row. The diagram starts on the left side.
While neither stitched sample on Instagram is snow, they are ground covers and are great examples of how this stitch works. The first is a dirt path on a J. Mahalay piece.
The second is the sand from Melissa Shirley's Beach House.
