One of the projects that has been swimming around in my head was this "square" style hat, also called a jester hat. I couldn't resist entering the Instructable Robot Contest so this Instructable is a product of the two.
While I was creating the robot hat, my children kept thinking of other characters that were yellow, including Sponge Bob, Minions, and honey bees, and just like all children, my oldest thought outside the box and said we could turn one of these square hats into Wall-E.
Whew. Now instead of one hat to make, I ended up making three. The bee & the minion are going to have to wait. They're not really square anyway right?
As I write this Instructable, it's topping 100-degrees in the part of California where I live, and my kids still wanted to wear the hats you see.
I think it's safe to say that my kids have gotten so used to me making Instructables and using them as models that they've grown to appreciate the little robot that brings me joy to share things to make with them.
I consider this pattern an easy pattern, and if you need crochet help, search this site or you can use one of the Instructables from this Collection: How to Crochet on Instructables.
It took me about two hours to crochet each cap/beanie. Depending on the style of the hat, the embellishments took me anywhere from two (2) hours (Instructables Robot), four (4) hours (Sponge Bob) or six (6) hours (Wall-E) to make and sew on, but I was taking photos in that time too.
As with all of my free patterns, please feel free to make and sell anything you make from these patterns. Do not use my photos and do not call this pattern your own. In all cases, please give me credit for the pattern and better yet, link to this Instructable.
