Alright, get your hoodie. Mine is fresh and clean, as I did laundry today.
Flip it over.
On the left side, do the standard clothing fold: one side over, and bring the arm down. You got it.
Repeat. Your hoodie should be somewhat straight and neatly aligned.
Now for the tricky part! FOLDING. Rather than folding 3 sections equally, you're gonna fold just 2! I know. It will work! You're reading my snap-guide remember? So, fold one end short (!) like this...
...and fold the rest over snugly. Two sections. Great job. I like a firm pillow. If you want it loose, don't fold as tight.
Almost there kids. Now, take the actual *hood* of your hoodie, and cover the lower half you folded. For fun, I made mine peak like this. It isn't necessary.
Flip it over. Shove the folded part into the hood. Like a stack of papers going into a pouch.
Tightly pull those hoodie strings you never use!
Lo and behold! You have a pillow.
There it is. The solution for an aching neck, and heavy head on car rides and other travels. Save your $8 and make a hoodie pillow.
