I started with little onesies. Tony played football for Missouri Western (black and gold) and was #41.
When I applique, I always iron the Wonder Under to the fabric first and when it cools off, the paper peels right off for you to mark your pattern.
Remember if you mark on the back to turn your pattern upside down.
Iron it on and just zig-zag around the outside.
I did a more detailed tutorial Here on all the steps I do when I applique.
