Does anyone have a link to the one hour scarf, please?

[DrSeuss]

I have a scarf made by a friend who has since moved away. About 18" long and made of fluffy yarn, has a slot to thread it round your neck, supposed to take one hour to make. Does anyone know of such a pattern, please?

like this? or

The second is a specific scarf yarn that has instructions on the ball band and there is a youtube video for this kind of yarn
