Yarn Substitution Question!


I bought the Anise pattern from Rowan and I was wondering if anyone had any suggestions on what I could substitute the rowan big wool yarn with ? My LYS doesn’t carry it and I looked online and it’s very pricey !!!
The yarn doesnt neccesarly have to be wool - I have very sensitive skin.
I also thought of maybe doubling some yarn but i’m not sure where to begin with that.
Any help would be great !
Thanks !!!
