Here’s a card I did for my sister’s birthday. She has a cat. The cat does this to her. That cat can’t believe its luck!
I used a thicker nib for this, and coloured direct with markers, which can lead to a bit of smudging, but does make for a nice final card (I think so, anyway).
Update: You can now buy this cartoon on a t-shirt, hoodie, or sticker at RedBubble. How can you resist?
