Two Color Cable Scarf (I_Cord)

Here’s the link: http://www.ravelry.com/patterns/library/two-color-cable-scarf

I’m considering getting an embellish knit i-cord maker to be able to make Things very similar, and was wondering if anyone had a link to a free pattern for something very much like this. I’d like to try out seaming i-cord together in this manner before I commit to a new piece of equipment. Any suggestions?

Thanks in advance.
