Yarn sub question

I want to make the gellato pattern from Fiber trends. It calls for double stranding either two strands of wool or a strand of wool and a strand of mohair. I have this wonderful tweedy blue yarn from Maggi knits that’s acutally a bulky weight. Can I use a single ply of that as long as my gauge adds up right? I need to knock down some of the stash and thought this was a good way.

Thanks!

As long as it knits up to gauge, has the same qualities of the yarn called for, and you like the effect, than, yes, you can use it.
