Shawl size?

Hi everyone!

I’m still knitting the Kinetic shawl (found at Knitty.com), but I don’t know how long to make it… It’s 41 cm (16 inches) wide. How long do I make it? Is there a way to know if the size is enough as it is? (Maybe comparing it with my arm’s length or my body size? It’s for my mom and we have practically the same measures)

Please help! (I want to BO this shawl so bad!)

Usually you want the shawl to be about finger tip to fingertip which is about 5-10" more than your height.

Thanks, I’ll keep on knitting then. (I’m so close I can feel it! No sleeping for me tonight :D)
