Their bodies are primarily pom-pom balls, most limbs are pipecleaners or a specific type of pipecleaner called a "chenille bump" or "bumps", and their eyes are either vintage googly eyes I found at a flea market (but are easy to find online!) or black plastic fork prongs :3 a detail here or there is a small piece of fleece!

put together using low-temp small hot glue gun! Anyone could have fun this way I think w one can trim pom-pom balls into a desired shape, provided you don't cut too close to the center and unravel the entire ball.
One can also intentionally unravel a ball to utilize just the fluff on any random area it is desired!
