Hi Vickat. The one Redhead helped me with is very heavy as it uses grannie squares plus additional stitches. Here's the link if you want to see it. Reminds me of my past "hippie days"... I saw that Pixieglitter posted a light summer poncho (link:
Ravelry: Summer Fun Poncho pattern by Tammy Hildebrand). The pattern was free also I believe. So maybe between these you can find one you like! Very cute poncho Pixie!
