I can’t really comment on hooks because I’m fairly new to crochet too. I just bought a set of crochet hooks in a case so I’d got all the different sizes but since I mainly seem to use a 4mm hook, I’m hankering after one of the Clover ones with the cushioned handle! (Is it sad that I now yearn for comfortable-to-use needles and hooks? I suppose it’s better than not being able to walk past a stationery shop without being compelled to buy some new kind of pen!)
I’ve arranged for someone to do a crochet demonstration at my knitting group next week. 2 of us have taught ourselves but the others want to learn and I’m hoping to get some clarification on how to use the charts!
Good luck with your classes! I’m sure you’ll get it in no time!
