Small spaces are often the most challenging spaces to be creative. I have a variety of go-to stitches for small spaces and get overly excited when I can add to that library.
I discovered this stitch last night as I thumbing through books for a new piece I'm working on. The beauty of this stitch is that it works as an open stitch with a lighter thread and a skipped row (as diagrammed) or as a full coverage stitch with a heavier thread and no skipped row.
I'm using it for a sky but it would work really well as ground covering (grass, dirt, or even snow).
