Here is a post from the Club Penguin Blog. It shows how Screenhog make items. It originally showed how Screenhog designed the Tuba. I designed an Orange Inflatable Duck and changed the pictures and some text.
Hello Penguins. Screenhog here.
Decide, Design, Draw, 3D… We thought you might want to see how we make an item for Club Penguin:
Step 1: Decide. Usually, items are related to what events are happening that month, or where it will be used (like the costumes in the Costume Trunk).
Step 2: Design it. A rough drawing is made of what we think the item should look like (in this case, an Orange Inflatable Duck).

Step 3: A final drawing is made. This is a clean-up of the rough drawing, with detail, color, and shading added. The icon is also made (this is the drawing of the item that’s in your inventory).
Step 4: The clothing item is then made in 3D.


Finally, it’s done!
Are there any clothing items that you’d like us to make? Are there any older clothing items that you would like to come back?
Until then…Waddle on!
