I whipped out this afghan a while back (it really is fast) using 2 strands of 2/12 Tamm yarn. I have a lot of Tamm, and am quite happy with how it works, not just on my standard gauge machine, but on my bulky and mid-gauge machines. For the bigger gauge machines, I use more than one strand.
My afghan has a wide, sturdy hem that gives it a much tidier finish than an edging or a fringe would, at least for this yarn and this stitch.
If you have a DK weight yarn or even a worsted weight yarn, you could make this afghan. Mine took about 3 pounds of yarn total, about half of that the lighter rose and half the darker burgundy.
The afghan also has latched joins and latched sides. They're easy to do, have an interesting look, and also go quickly.
