Oooh, @lucysmam - that top needs a really special yarn! Go for it!
I'd love to use more natural fibres, but neither DH nor DD will wear wool of any kind, which does cut down my choices. DH has requested a jumper, and the recommended yarn would cost over £80 for his size. Now, I don't mind spending the money as such, but spending the money on something that ends up being a bit shit because I'm not quite good enough yet is another thing entirely!
For this reason, when I move onto the Marzanna sweater in a few weeks time, I'm downgrading my yarn choice from Long Cole Luxury Merino to James C Brett DK with Merino, which is about 70% cheaper, mostly due to containing 90% less actual merino wool
.
Still, I'm currently working in cotton for the Aviva, and next after that will be a Granny-Go-Round dupe in cotton bamboo, so it isn't all bad news.
