I kind of understand the basics eg creating the starting ring and how to do the stitches, the principles of increasing, etc, but now need someone to tell me which hook size will work with chunky wool. I just started one using a 5.0mm hook but the edge was wavy rather than bowl shaped - does this mean my wool is too thick? The pattern says worsted wool, but if I use the chunky will I need a bigger or smaller hook?
In case it's not obvious, I'm a beginner.
