I've tried this: This is a GREAT origami tutorial for a fox. It gets a little bit confusing, so I don't recommend it to total beginners, but ultimately it makes a cute origami fox that can stand up on its own.
Jenny: This is interesting envelope package because it's heart shape normally the envelope it's rectangle or square shape . The good thing is the heart shape also can be a rectangle shape. but when you open it . It is a heart.
