I think I planned on making the Hitofude cardigan for my daughter and the amount of yarn would be right for that. However, since I bought the pattern and have looked it over, I think I'm changing my mind, it sounds incredibly complicated, not the lace pattern, but just the way it's put together. I'll look again, but I might have to make something else out of it. At least I remembered, so that's a step forward!
I've considered that one too... it is pretty and there have been many made
