It turns out you really do get what you pay for when it comes to wool. This is some Misti Alpaca variegated laceweight that I bought from an actual wool shop in Canberra, and a beautiful silk merino blend that I got from Ice. The silk merino isn't quite as gold as I thought it would be, but still pretty. And the alpaca is beautiful. I wasn't sure how they would be on the warp, because they both have a bit of fluff, but it worked well.
I did stripes on the warp and alternated one row of each on the weft. It is very soft and light and lovely.
And I still have some of each left over!!! I will have to think of a project for them - perhaps not the two colours together again because I think the gold drained some of the prettiness out of the variegated one.
