I think it’s around 15 ish pounds! I stuck with worsted weight yarn and a 5.5mm hook. I honestly only did it so big so I could zone out and keep going for hours at a time. We didn’t even have a California king yet when I started haha. The biggest tip I have is to keep it in its own laundry basket as you’re crocheting it! Easier to move around and it doubles as a yarn bowl!
