Red heart yarn has team color combos that have been all over Joann's and Walmart for over a year or two now. I bought the red and white combo for the Autobot scarf I made a few months back and the purple and white combo for the Decepticon scarf shown below.
I used a medium rectangular loom and used 14 rows.
This was the progress earlier tonight. I tend to loom knit faster than I do crochet.
I added some tassels at the ends and didn't want to make this too long.
Because I am still learning how to do patterns, I didn't knit in the insignia. Maybe I will try that in the future as my knitting improves. Thus, I hot glued the patches on the bottom of the scarf.
And the end result........
