This poncho can make one in a weekend using a big hook. It is fast and easy. Just pop it over your head to keep you warm when the wind gets chilly or the air-conditioning is too cool. Make one in super soft machine wash wool for every day and every evening or glam up your outfit with one done in silk. It is worked from the neck down in one piece which means no seaming

This pattern uses 11.5mm hook.
Other yarn suggestions: Noro Kureyon or Indian Silk Shop Machine spun recycled sari silk.
