This scarf combines lace and texture in a simple, grid-like pattern. You just replace the center stitch in every little box of the grid with a yarn over. It’s a six-row repeat worked over a multiple of 4 stitches, plus 1 (not including border stitches).
You will need 350-400 yards or about a hundred grams of fingering weight yarn to get a light scarf.
(You can cast on more stitches if you want a wider scarf or stole, in which case you will need more yarn. Another possibility is to omit the garter rows at the beginning and end, and seam the ends together to make a cowl. )
