It seems everyone's got this scarf on their wists, so I decided to make my own version. Mine turned out a little too skinny (~3"/~7.5cm) and a little too long (~7'/~2.2m before adding fringe) so I'll probably end up making another one.
A close-up of the cloud:
It's a pin (or brooch, or whatever )
The scarf was simple enough, w/ J-hook and worsted-weight yarn, ch243, dc across, changing colors at end of each row.
For the cloud I made a circle, elongated the ends (hdc,dc,tc,tc,dc,hdc over 3 sts, do once on each "end" of the circle to make an oval) then repeated a few more times to make the cloud "bumpy."
The whole thing took maybe 6 hours.
