What to knit with Biggie Super Bulky Yarn?

I bought 3 skeins of it, but it’s not enough to make a blanket and appears too chunky to make anything but a scarf. Any ideas?

Additionally, the skein of yarn is twisted. Would it be a bad idea to untwist it to have thinner pieces?

Welcome,
There are several ideas on Ravelry. You can narrow the search by putting in your yardage. Hats, cowls, mittens.

I’m not sure what you mean by twisted, the yarn is plied, strands wrapped aroun each other? That adds strength to the yarn.

When you’re buying a yarn that is a less common size it’s usually best to have an idea of what you are making and how much you need. I wouldn’t unply it. It loses strength and will pull apart/break easy.
