I had some family at my house this week and my niece kept wanting to play my ukulele, only she called it "kookulele". It made me laugh every time and in the morning before they got up I sketched this real quick to remind me of it.
I took an hour or two and drew some owls while watching the 7th Harry Potter movie. The black (it's actually dark purple) ink is in a Platinum Preppy refillable marker (I SWEAR BY THESE -- you just need the ONE and can keep putting ink in it) (https://www.gouletpens.com/collections/other-writing-instruments/products/platinum-preppy-refillable-marker-black?variant=11884751487019) and the green is in an extra-fine Lamy Al-Star (https://www.gouletpens.com/products/lamy-al-star-fountain-pen-bluegreen?variant=11884855885867).
