yarn vs thread in yoyo afghan

I have been asked if this can be done in yarn, as opposed to thread. The answer is yes; here is an example I made to answer this question. The little two-round yoyo is the same yoyo square from the tutorial. The red white and blue square is sugar and cream cotton yarn that I used an H hook with. Why this color choice? It is left over from last 4th of July and some triangle hair scarfs I made for a swap. Figured it was a good way to use up the yarn and still have something I could use, even if it is only at patriotic holidays.

In the first photo I have them side by side; in the second photo I have the thread square sitting on top of the yarn square. As you can see, two rounds of thread equaled one round of yarn. So this tells you that using this yarn will work up four times faster. The same number of rows that I used for my square would be a nice size for a infant newborn car seat, maybe a few rows would need to be added but not many using sugar and cream yarn. Other yarns might need a few more rounds than that.
