I think the top right goldfish is staring at me...eeh.
It only cost me $ 0.99 ! Time investment? About an hour.
I made a stencil using this goldfish , drew it onto the fleece, and cut it out. I hot-glued googly-eyes on! I cut out little felt "bubbles" and hot-glued everthing in place. Very minimal sewing! (Just the basic pillow).
This idea could be used for a lot of different animals. Hope it inspires you to create something fluffy!
