I ended up making my own, it was surprisingly easy and fun.

I just bought the fattest thickest yarn available at micheals and finger knit it into a giant blanket. With it being so thick it was easy to just work my way back and forth knitting it by pulling loops with my fingers.

I went overkill and used too many skeins and now it won't fit in my washing machine, so I can only wash it at the laundromat on the turbo size machines. Also when it's wet it takes my fiance and I combined to lift it.

But hot damn is it amazing, it's both heavy as hell but breathes really well so I don't get too hot under it. And it's large enough I can fold it in half for double weight/warmth if I wanna just cook myself like a lil bean burrito.

Highly recommend it, it's a fun beginner project.
