Definitely want to make some capes from adult tee shirts. If cut the neck and add velcro for safety though. No-Sew Superhero Cape from a t-shirt. The post has a tutorial for toilet roll superhero cuffs too.
These are hero capes. You can color print them on cardstock, cut them out, make a hole where it should be and tape them to lollipops to make superhero lollipops. Cut out corresponding colored masks, as well.
