Common questions

Which chipmunk is which?

Red + A is the leader, blue + S is the cool one, green + T is the chubby one. Line up tallest to shortest in that order and the reference lands.

No iron, can I still do the letters?

Yes: cut the letters from felt and fabric-glue them on, or safety-pin paper letters. Iron-on is cleanest, but glued felt survives the night.
