This was made using a single stitch and two strands of 2000 ypp chenille yarn - one acrylic (oatmeal) and one rayon (tobacco). I didn’t use a pattern. I just chained it as wide as I wanted and then kept crocheting until I ran out of yarn. When I washed it, the rayon yarn shrank. The acrylic yarn formed all these random loops which gave the whole afghan a really cool shaggy look.
