So, to try it out, I bought some Moda Vera Clermont yarns from Spotlight. It is 75% wool, 25% polyamide, and comes in 4 colour mixes: Purple Mix which I bought, as well as the Red Mix on the left of the photo below, Pink Mix on the right and a Rainbow Mix not in the photo.
I have read somewhere that you will need 2 balls of the Clermont yarns to arm knit a scarf. However, I ended up with some leftover yarns from the second ball as I didn't want mine to be too long. Here is the video clip that taught me how to arm knit:

...and this is what I knitted!
I am now a little tempted to french knit different combination of yarns and arm knit them into more chunky scarves!
