I found links to the ones I mentioned earlier if you want to peruse them. You can probably find them at other outlets online and in the 3-dimensional world, but this will give you an idea what's available.

*A note on this one, it's superwash, but I'd recommend washing it either by hand or at least by itself the first time around. I've only used it once, but it turned my fingers and (bamboo) needles green as I was knitting it and turned the water green when I washed it to block it. Could be that I just got some extra dye for free in the 2 skeins I got. I've only used it once, and I haven't noticed having the same kind of bleeding in any of the others I've listed. But it won't hurt to wash it solo the first time anyway.
The Cascade 220 Sport is a lighter (DK/Sport) weight (that technically should be called Cascade 292 if they followed their usual convention). You could still use it, but you'd have to adjust for the lighter weight somehow. By my calculations, it's about 25% thinner than Cascade 220.
