This simple garter-stitch scarf is a modification of the popular Miss Marple or Key Hole Scarf. My husband likes it because it stays up around his neck without long tails to flap around or get in the way but has short tails that easily tuck inside his jacket to keep his chest warm.

Using a size 6 (US) needle with LionBrand Tweed Stripes or Scarfie yarn (5 Bulky) makes a dense fabric that is nice and warm even with an acrylic yarn. It takes about 1 skein of Tweed Stripes, but you can get two or maybe even three out of a skein of Scarfie.
Finished size approximately 3 3/4” - 4” wide and 48” or 49” long, or desired length.

This pattern could be used to make a smaller scarf for a child if a smaller needle, perhaps a size US #5 with worsted weight yarn.
