4 Balls of
GGH Modena This yarn is now discontinued.
This yarn is great to work with! It's machine washable and ON SALE, so you can't beat it. We used 4 balls and made the poncho without a hood - although you could easily add a hood with 1-2 more balls of yarn.
I made the smallest size, but because the yarn is thicker than the pattern calls for, it ends up being the middle size...
