This Penguin Costume is so cute. It will make a great party costume for your little one. It is all the more appreciated when you make things yourself and all the more satisfying when you save money whilst your doing it.
I would say that you would probably need some sewing experience for this project. The reason being, you would need to print and assemble the pattern and there are lots of fiddly little bits to sew. If your not used to this, it could be a bit tricky. If this project matches your skills, follow the link for the tutorial; Penguin Costume
