I made this poncho with Lion Brand Coboo Lichen. I used 580 yards (530 meters) and my size is at the time I wrote this pattern and made the poncho was a 2X-3X. I used a 4.0 mm or a G hook. You can use any yarn and any hook you want. If you have any questions about this poncho, you can email me at crochetingwithleeann@gmail.com. Thank you.
