1. Nose: Don't freak out about the nose. All you have to do is pinch the face together and fold it up to create the signature pug nose. Here is a video that demonstrates this technique.
2. Stuffing: I actually wish I had stuffed my pug a bit more, especially in the chest. The legs can also be liberally stuffed, since they are what keeps the pug standing. I used Fairfield Poly-Fil Premium Polyester Fiber stuffing.
3. Seams: The seams were a challenge for me. I had never done mattress stitch before. I used this video to learn how to do the stitch, and then just went off pictures. I want to work more on this aspect if I make another pug.
My next knit pug will definitely be a black pug, like this guy by hiro25neko.
