Mistake #1: It's nowhere a beginner pattern. It says that intermediate skill level is required, but due to quite a variety of patterns it's more than just increases/decreases that you have to do. Knitting is math.
Mistake #2: I've chosen a different yarn. The yardage is almost exactly the same. It's 312m per 50g. The mix is pretty much the same, except for the 37 % viscose bit instead of 40% wool. I want this to be a summer top. And who wants a wool top for summer, right?
When I checked my gauge on 8mm (US11) needles, I noticed that it was all just wrong. That was way too airy, and it was pretty clear that taking three or four strands of yarn (instead of two) just wouldn't help. It all looked like a fishing net! So I tried smaller needles. Way smaller. At the moment I'm knitting on 2.5mm (US1.5)! Yes! This means I have to do loads of modifications.
Despite all the trouble, I like the way the pattern looks like and the shape that the whole "thing" is taking. I like that it's thin and light. This will be a wearable top (fingers crossed). I hope.
