@CrochetBug Yes, as much as it looked a bit scary, I think at least part of that is because it is really, really comprehensive so there is A LOT of information. But if I take it step by step, it should, I think, be fine.
@GlowWine I know what you mean about the stripes! I'll give it a bit more thought, while I do my (totally pointless, because it won't actually match what happens when I start the garment) gauge swatch.
This is the yarn that I have. LoveCrafts are selling off all their Deramores very reasonably, so I'm tempted to pick up a couple more balls in a complementary colour to make it a bit more interesting, and also because I always, always run short.
