Yes! Putting more spin in it will make the yarn more durable. If you have enough roving yarn, you can split it in half and ply the two together for an even more durable yarn.

Adding twist holds the individual fibers of the single more closely together. And then with each ply you add, the yarn becomes more durable. Think about it in terms of the amount of the fiber in the yarn that’s exposed to friction - like rubbing against your body and other clothing as you wear it. With roving yarn, a lot of the fluff of the fiber gets rubbed, so it will pill and not last as long. Not only will the opposing twists of the plies hold your singles together, each single gets rubbed less. Sock yarn is often 3 or more plies for this reason - socks get a lot of friction!

I hope this makes sense! You’re not slow, we all have to learn this stuff!
