Tweed Stitch Variation
The last stitch for March 2026 is called Tweed Stitch Variation. It's not a snowflake stitch, but it would work well as a snowy background, or you could omit the X stitches for snowflakes falling. Sheena posted this with a Merry Christmas to her Pinterest account so she was thinking of sparkles and snow and the holidays, making this a good choice to finish the month.
Sheena has given you the stitch path for both stitches on the right of the diagram. This would look very nice in two or three threads of a similar color for snow, perhaps a white, a silver and a white metallic. You could dress it up in three contrasting colors for clothing, however.
