T-shirt yarn swatching

Even though the t-shirt yarn class I am taking (which ends next Monday) comes with four custom (and customizable) patterns that Stefanie designed specifically for the class, I wanted to swatch some of my yarn just to get an idea of how it looks. I knitted up one of the balls on size 10.5 needles:

As you can see, the lowest portion is garter stitch, which looks good. The middle section, the stockinette, I am most impressed with. It looks really nice for what this yarn started out as! However, seed stitch (the uppermost portion next to the needle) is not this yarn's friend. It looks like crap. Which is OK, not every stitch is for every yarn.

The lightest weight yarn you can really make without breaking the material is about a heavy worsted. I would say what I have knitted up here is a bulky. The most WPI I have been able to get is 6.5, and this yarn is about 5.5 WPI (wraps per inch - wrap the yarn around a ruler and it helps you get an idea of yarn weight - fewer wraps = heavier yarn).
