You don’t necessarily need to create a separate page to display your items. First create a group in Step 4 such as coats, and list all of your items in the group. Then go to step 3 and click on organise pages. You will see down the left a list of all your pages including the groups you created in step 4. Simply drag across to the right the pages/ Groups you want shown. There is a small video within organise pages that will show you how.
Alternatively you can create your own groups page by adding images and text to the page. Although you will still need to create the item and link to it. This has the advantage of giving you more flexibility with the layout but you will use up your pages quickly.
