Once you have created a Collection, you can always edit it and keep making changes to it so that you get the perfect Collection.
Within a Collection, you can edit the text that is an integral part of your Collection.
Notice the 'Edit Collection' button at the top right of your screen. Click on it to edit the text (change the font, headline, add/delete to the text that's already existing). All of this is super-easy within Paperflite.
