Yarn for Double Moss Stitch

I need a little help. I have already knit Knitty’s Couvercle in Rowan Alpaca Soft. It’s really nice and my sister would like me to make her one too. I think that a dramatically verigated wool would be too busy. The pattern calls for an aran/chunky yarn and it’s for winter wear but wool is too itchy for here so a wool blend would be ideal. I was thinking Borroco Trilogy because I think my sister would like the bit of giltter in it, but I am open to any suggestions. Thanks so much.
