Matcha Cookies Help?

Okay, so I want to make these cookies that Maki posted ages ago because I'm addicted to matcha and these look delicious. However, I'm a bit stuck on the amounts. I'm from Canada - we don't use scales in our cooking (here in BC if you own a scale it's seen as.. dodgy). So I'm at a loss as to how much of those ingredients I'd need. Normally I'd just guess, but baking is a lot more precise than cooking, so any help would be wonderful.
