This scarf was made by single crocheting across a row of chain stitches that were set to the wanted width of the scarf.  The row of single crochet was repeated until I got to the desired length.   I used Red Heart Baby Clouds Yarn in Water Baby for this cool green color.  I found this yarn very difficult to deal with because of an invisible thread that ran through the center of the yarn.  This also made it very difficult to take out stitches to make a mistake.  Regardless, the scarf came out very soft and warm.
