to view the little cardigan at Ravelry. The yardage needed ranges anywhere from 696yds to 1044 yds, with sizes ranging from 30/32 up to 40/42. You didn't mention what size you'd be shooting for.
Unless you're petite (aka, slim
) 838 yds is rather limiting for a cardigan.
Browse Ravelry patterns and type in "cropped", meaning waist length. For either pullovers or cardis. That's how I found the little Noro cardigan.
