These instructions include a significant amount of details, including gauge, making a cuff for a hat, and the embroidery details for all three types of characters.

Please check your gauge! I used an H-hook for the hat and a G-hook for the details.

Other embellishments were made of felt and embroidery.

I included photos for creating the Instructable Robot hat, Sponge Bob Square Pants hat and Wall-E type hat.
