You can use any yarn and needles you like to make a garter stitch scarf. If you choose a chunky or bulky weight yarn and larger needles, your scarf will knit up faster. It is also easier to work with larger needles and heavier weight yarn if you are a beginner. A light colored yarn is recommended for new knitters, because the stitches are easier to see.
If you would like to make the scarf knit in the video, here is what you will need:
One (1) 5 oz. skein of Caron Simply Soft Chunky (Yarn color in the video is Lavender Blue)
One (1) pair of US Size 10-1/2 needles
A yarn or tapestry needle for weaving in the loose ends
Approximately 51-1/2 inches long, 5-1/2 inches wide
Cast on 20 stitches
Knit until you have approximately 1 yard of yarn left. Bind off, weave in loose ends. Your new scarf is now ready to wear!
Here is the video. Happy Knitting!
