Use a spoon to fill a bottom corner of a sandwich bag with a filling.Snip off a small bit of the corner with scissors to create a piping bag. Each sandwich bag holds one sandwich filling: peanut butter, Nutella, marshmallow Fluff.
Twist close the open end of the sandwich bag.This is to make sure the filling doesn't ooze its way out of the bag as you're squeezing.
