"What hook size do I use?"
Answer: Whatever size you want to use! The cool thing about doing graphgans in either sc or C2C is that your hook size (either larger or smaller) doesn't mean the success or failure of your project!
The hook size you use will change the size of your project only! So, if you want a larger blanket or item, go with a bigger hook! Simple as that!
